Terms of Use

READ BEFORE USING THE PLATFORM

DDDIMO is an online marketplace. DDDIMO does not manufacture, store, inspect or sell the products, digital files, courses, services or events made available on the Platform. Every sales contract is concluded directly between Buyer and Seller.

When you acquire a digital file, you are not acquiring ownership of the design: you acquire a limited, revocable licence to use it, the scope of which depends on the licence type selected at the time of purchase.

These Terms contain limitations of liability and, in certain jurisdictions, dispute resolution clauses. Rights granted to consumers by mandatory law are not affected by these Terms.

1.2. Technology platform operator and merchant of record

DDDIMO operates on the technology infrastructure of Cobuntu, which acts as platform operator and as merchant of record.

Cobuntu collects Buyer payments, holds them in escrow for the applicable refund window and transfers each Seller's net share to their connected Stripe account. DDDIMO does not collect, hold or transfer funds. The full allocation of roles is set out in clause 3.

2. SCOPE AND ACCEPTANCE

2.1. These Terms of Use (the "Terms") govern access to and use of dddimo.com, its subdomains, applications, programming interfaces and all related services (together, the "Platform").

2.2. By creating an account or by accessing or using the Platform in any way, you confirm that you have read, understood and agree to be bound by these Terms and by the documents incorporated under clause 3. If you do not agree, you must not use the Platform.

2.3. Acceptance is given once, at registration, by an unambiguous affirmative act. DDDIMO retains an electronic record of that acceptance, including the document version accepted, the date and time and the user identifier. Certain operations, in particular publishing digital files and acquiring digital licences, require additional, specific acceptances under the applicable documents.

2.4. These Terms apply to all users, whatever role they take on the Platform: Member, Buyer, Seller, or any combination of these.

3. CONTRACTUAL ARCHITECTURE AND INCORPORATED DOCUMENTS

3.0. Two contractual layers

The legal relationship between you, DDDIMO and Cobuntu is organised in two complementary, not alternative, contractual layers:

You are bound by both. Neither replaces the other. The Cobuntu Terms of Service are incorporated into these Terms by reference, in the version in force at the date of the transaction.

3.0.1. Allocation of roles

3.0.2. Precedence

In matters of payments, escrow, payout schedule and execution, recovery of amounts and technical operation of the platform, the Cobuntu Terms of Service prevail.

In matters of digital file licensing, refund eligibility and scope, risk classification, product safety, intellectual property, prohibited content, moderation and DDDIMO's liability, these Terms prevail.

In matters of published plan prices, seller-fee percentages, annual billing totals, and the amount and eligibility of the founding offer, the Pricing Specification (P01) is authoritative. The Fees, Payments and Payouts Policy (D11) reproduces those figures and may not contradict them; where it does, P01 governs until D11 is corrected. The fee base, what the fee includes and the minimums are set out in clause 17.4 and reproduced in P01 and D11 on the same basis.

Where both documents apply to the same matter and can be applied together, they apply cumulatively. In the event of an irreducible conflict, and where you are a consumer, the solution more favourable to you prevails, subject to clause 18.

3.0.3. Changes at the platform layer

DDDIMO does not control the content of the Cobuntu Terms of Service. On becoming aware of a significant change affecting the rights of DDDIMO users, DDDIMO will communicate it under clause 25 and, where necessary, amend these Terms accordingly.

3.1. Incorporated documents

3.2. Within the marketplace layer, and in the event of conflict, the following order prevails: (i) mandatory legal provisions applicable to you; (ii) the jurisdictional Annexes to these Terms; (iii) the category-specific terms; (iv) the terms applicable to your role; (v) these Terms. Articulation with the platform layer is governed by clause 3.0.2.

3.3. The current version of each document is permanently available on the Platform, with its version number and effective date. DDDIMO maintains a public archive of previous versions.

4. DEFINITIONS

For the purposes of these Terms and all incorporated documents:

Buyer, a user who acquires, or intends to acquire, a Printed Product, Digital Licence, Course, Service or Event Ticket on the Platform.

Course, educational content made available in the Learning category, including PDF materials, e-books, tutorials, guides, video, links to content hosted off-Platform, and live training.

Digital File, a digital manufacturing file or three-dimensional model, in any format (including STL, 3MF, STEP, OBJ, F3D), made available on the Platform for download under licence.

Digital Licence, the authorisation to use a Digital File granted by the Seller to the Buyer, within the scope and limits of the licence type selected (B1, Personal Use; B2, Commercial Limited; B3, Commercial Unlimited; or a custom licence).

Event, an in-person or online event promoted by an Organiser, access to which is sold on the Platform as a Ticket, including fairs, congresses, workshops, meetups and conferences, together with exhibition stands and sponsorships sold through the Platform.

Member, a registered user who does not transact, participating through the Platform's community features.

Organiser, a Seller who promotes an Event.

Printed Product, a tangible good, whether or not produced by additive manufacturing, sold on the Platform, including printed objects, machines, materials, filaments and accessories. Referred to in earlier versions of these Terms as a Physical Product; the two expressions have the same meaning.

Professional Seller, a Seller acting for purposes relating to their trade, business, craft or profession.

Seller, a user who offers Printed Products, Digital Files, Courses, Services or Events for sale on the Platform, whether as a professional or as a non-professional.

Service, work commissioned from a Seller and performed for a specific Buyer, including printing on demand, scan to CAD, three-dimensional modelling, finishing, engineering and consultancy.

Service Provider, a Seller who offers Services.

User Content, any content uploaded, posted, transmitted or otherwise made available by a user on the Platform, including digital manufacturing files, images, renders, descriptions, text, video, reviews and communications.

5. ELIGIBILITY, AGE AND CAPACITY

5.1. Minimum age. Creating an account and using the Platform require a minimum age of 18 and full legal capacity to enter into contracts. This requirement applies to Members, Buyers and Sellers without exception.

5.2. Basis for the requirement. The age requirement does not arise from the nature of the content made available, the Platform hosts no content unsuitable for minors, but from the legal nature of the operations carried out: concluding sales contracts, granting and acquiring intellectual property licences, making declarations of rights ownership, receiving payments and meeting tax obligations. Contracts entered into by minors are voidable under Articles 123 to 125 of the Portuguese Civil Code and equivalent provisions in other jurisdictions, which would undermine the validity of licences granted and acquired through the Platform.

5.3. Age verification and protection of minors. DDDIMO requires a declared date of birth at registration and applies proportionate verification measures wherever there are indications that a user is a minor. The Platform does not display profiling-based advertising to users identified or reasonably presumed to be minors (Article 28 DSA). In Brazil, self-declaration is not permitted as the sole age-verification method under Law No. 15,211/2025, see Annex B.

5.4. Minors' accounts. On becoming aware that an account belongs to a minor, DDDIMO will suspend it immediately, cancel pending transactions, refund sums paid, revoke licences granted and delete the associated data in accordance with the Privacy Policy.

5.5. Sanctions and excluded territories. You may not access the Platform if you are subject to restrictive measures or sanctions imposed by the European Union, the United Nations, the United States or the United Kingdom, or if you are located in a comprehensively embargoed territory. DDDIMO does not operate in the comprehensively sanctioned territories identified in the Anti-Fraud, AML and Sanctions Policy, which is kept up to date.

DDDIMO further reserves the right to refuse registration, or to restrict Seller activity, for users domiciled in countries and territories listed as non-cooperative for tax purposes by the European Union or the Portuguese tax authorities, and in jurisdictions not covered by the payment service providers used by the Platform.

6. ACCOUNT

6.1. Registration. Registration requires true, accurate, current and complete information, which you must keep up to date.

6.2. Security. You are responsible for the confidentiality of your credentials and for all activity carried out through your account. Notify DDDIMO immediately at security@dddimo.com of any unauthorised use.

6.3. One account. Unless DDDIMO expressly agrees otherwise, each person or entity may hold only one account. Creating accounts to circumvent a suspension or termination is prohibited.

6.4. Closure by you. You may close your account at any time through account settings or by writing to support@dddimo.com. Closure does not affect: (i) obligations already incurred; (ii) Digital Licences already granted or acquired, which survive under clause 11.6; (iii) orders in progress; (iv) statutory data retention obligations.

6.5. Electronic communications. You agree to receive communications relating to your account, transactions and contractual changes by electronic means, and accept that such communications satisfy any legal requirement of writing. Marketing communications require separate, freely revocable consent.

7. NATURE OF THE SERVICE: DDDIMO AS INTERMEDIARY

7.1. Core principle. DDDIMO is a hosting service provider and an online marketplace within the meaning of Articles 3(g)(iii) and 6a DSA. DDDIMO supplies the technology that enables Sellers and Buyers to conclude contracts with each other.

7.2. DDDIMO is not a party to the sales contract. The contract for any Printed Product, Digital File, Course, Service or Event is concluded exclusively between Buyer and Seller. DDDIMO is not a seller, manufacturer, importer, distributor, publisher, trainer, service provider or organiser, and does not assume any of the obligations that the law attaches to those roles, save where expressly stated otherwise in a specific offer.

7.3. No control over offers. DDDIMO does not manufacture, store, pre-inspect, test or certify Printed Products; does not verify the printability, dimensional accuracy, structural integrity or fitness for any purpose of Digital Files; does not validate the technical accuracy, currency or educational value of Courses; does not perform, supervise or guarantee Services; and does not organise, sponsor or supervise Events.

7.4. Allocation of obligations (Article 6a(1)(d), Directive 2011/83/EU):

The detailed allocation, including product safety and insurance matters, is set out in clause 3.0.1.

7.5. Seller identification. Each offer identifies the Seller and states whether that Seller acts as a professional or a non-professional, based on the Seller's own declaration.

7.6. Notice regarding non-professional Sellers (Article 6a(1)(c), Directive 2011/83/EU): where a Seller declares that it acts as a non-professional, consumer rights deriving from European Union law do not apply to the contract, including the right of withdrawal and the statutory guarantee of conformity. This notice is displayed clearly on the offer.

7.7. No disintermediation. You may not use the Platform to identify counterparties and then conclude or perform the transaction off-Platform for the purpose of avoiding fees. DDDIMO reserves the right to charge the fees due and to suspend the accounts involved. This applies with particular force to Services, where the parties are in direct contact before the work is commissioned.

7.8. Self-imposed limits, declaration of non-qualification as an economic operator. DDDIMO undertakes, towards users and authorities, to refrain from acts that would make it an economic operator within the meaning of Article 4(15) of Directive (EU) 2024/2853. Specifically, DDDIMO does not:

a) affix its name, brand, logo or any distinguishing sign of its own to products, packaging, files or file metadata; b) import products from third countries in its own name, or appear as importer in customs documentation; c) accept a mandate from a manufacturer established outside the Union to act as its authorised representative; d) provide fulfilment services, storage, packaging, addressing or dispatch, in respect of products it does not own; e) acquire, take title to or resell any product or file in its own name; f) modify, repair, reorient, rescale, convert, generate supports for or otherwise optimise files uploaded by Sellers; any editing tools made available are executed by the user, under the user's control, with the output attributed to and recorded against that user; g) grant licences over Digital Files in its own name; h) perform, subcontract or assume responsibility for any commissioned Service.

7.9. Curation. DDDIMO may organise, order, feature, group into collections and recommend offers. No feature, collection, badge, mark or classification awarded by DDDIMO constitutes a statement of safety, conformity, fitness for any purpose or product quality. DDDIMO refrains from using labels suggesting its own origin, technical approval or testing, describing where applicable only the process verified (for example "seller identity verified" or "seller has declared conformity") and never the outcome.

7.10. Documentation in the Seller's name. Invoices, receipts, shipping documents, order confirmations and transactional communications identify the Seller as the contracting party, DDDIMO acting solely as collection agent in the Seller's name and on the Seller's behalf. Packaging does not carry DDDIMO branding.

7.11. Warning as to professional status. Sellers acknowledge being informed that selling products, files, courses, services or events regularly through the Platform may qualify them as a professional or trader under applicable law, even where the activity began as a sideline. There is no minimum sales threshold: qualification follows from the regularity of the activity, its profit-making character and the organisation adopted, assessed case by case.

Where that qualification arises, the Seller becomes subject to obligations including commercial registration, formal accounting, invoicing, assessment and remittance of VAT and other taxes, product safety, and consumer protection. The Seller undertakes to update their status on the Platform as soon as the qualification arises.

DDDIMO gives no tax or legal advice and is not responsible for a Seller's failure to meet the obligations flowing from their status. Falsely declaring non-professional status is a serious breach of these Terms, deprives Buyers of consumer rights and exposes the Seller to liability towards them.

8. CATEGORIES OF OFFER

8.1. The Platform supports five categories of offer, each governed by specific terms that form part of these Terms:

8.1.1. Commercial labels. The Platform groups Learning and Services under a single commercial label, "Courses & services", because they carry the same seller fee. The grouping is presentational. The legal regime of each category remains distinct, and the specific terms in the table above apply separately to each.

8.1.2. The Journal and the Forums are not categories of offer. They are community and information features, carry no seller fee, and are governed by the Community Guidelines.

8.2. Precondition for category B. No Digital File may be published on the Platform unless, within the same upload process, the Seller: (i) expressly accepts the Seller Digital Licensing Agreement; (ii) declares, on their own responsibility, that they hold the necessary rights or sufficient authorisation; and (iii) mandatorily selects the applicable licence type, defining, for a B2 licence, the authorised physical unit limit. Absent any of these, publication is technically blocked.

8.3. Precondition for acquiring category B. No Digital Licence may be acquired unless the Buyer: (i) is shown a summary of the licence's permissions and restrictions before payment; (ii) expressly accepts the licence terms; and (iii) gives the consent and acknowledgement set out in clause 18.4. Each acquisition is assigned a unique License ID.

8.4. Mandatory criticality classification. Every Printed Product offer and every Digital File intended to produce a tangible object must be classified by the Seller, at the point of upload, into one of the criticality levels defined in the Product Risk Classification and Liability Framework (document D34), which forms part of these Terms:

The classification determines the applicable information, documentation and insurance requirements. Publication is technically blocked until a classification is given. Incorrect, negligent or deliberately false classification is a serious breach of these Terms and grounds for removal of the offer, suspension of the account and DDDIMO's right of recourse.

8.5. Application of the classification to Digital Files. The classification in clause 8.4 applies to the Digital File itself, regardless of who produces the physical object, by virtue of Article 4(1) and (2) and recital 16 of Directive (EU) 2024/2853, which expressly qualify digital manufacturing files as products. A file whose resulting object falls within Level 4 is itself prohibited.

8.6. Category C, Learning. Courses and educational materials, including PDF documents, e-books, video, text and links to content hosted off-Platform, are not subject to the classification in clause 8.4, except where they contain instructions for manufacturing, assembling, modifying or repairing objects, in which case the Seller must classify the resulting object and observe the applicable restrictions. A Course whose object or practical outcome falls within Level 4 is expressly prohibited.

8.7. Category E, Services.

8.7.0. Availability. The Services category launches separately from the rest of the Platform. Until it launches, Services may not be listed, commissioned or purchased, and the Platform states on the plans page and on the home page that service fees apply when the Services category launches. Nothing on the Platform may present Services as currently purchasable before that date. This clause 8.7 takes effect for a given Service on the date the category opens.

8.7.1. A Service is contracted between Buyer and Service Provider. DDDIMO is not a party, does not perform the work, does not supervise it and gives no warranty as to its outcome, timing or quality. Clauses 7.2, 7.3 and 7.8(h) apply in full.

8.7.2. Classification. Where a Service produces a tangible object, the Service Provider must classify that object under clause 8.4 before accepting the commission, and the restrictions in clause 13.1(d) apply. A Service whose outcome falls within Level 4 is prohibited, whoever commissioned it.

8.7.3. Files supplied by the Buyer. Where a Buyer supplies a Digital File in order to commission a Service, the Buyer warrants that they hold the rights or the licence necessary for that file to be manufactured, modified or processed for the purpose commissioned. A B1 Personal Use Licence does not authorise a third party to manufacture for sale. The Service Provider must refuse a commission where the Buyer cannot evidence the necessary rights.

8.7.4. Specification and acceptance. The scope, materials, tolerances, delivery date and price of a Service are agreed in writing through the Platform before work begins. Changes require a new written agreement. The Service Terms set out the milestone, acceptance and revision regime.

8.7.5. Substantial modification. A Service Provider who substantially modifies a file or a product becomes the manufacturer of the resulting product under Article 8(2) of Directive (EU) 2024/2853, with the obligations that follow, including those in clauses 19.10 to 19.14.

8.7.6. Right of withdrawal. Services are subject to clause 18.2.9.

9. RANKING OF OFFERS

9.1. In compliance with Article 6a(1)(a) of Directive 2011/83/EU and Article 5 of Regulation (EU) 2019/1150 (the "P2B Regulation"), DDDIMO discloses the main parameters determining the ranking of offers presented to Buyers.

9.2. Main parameters, in decreasing order of relative importance:

1. Textual and semantic relevance to the search terms entered.
2. Quality and completeness of the offer (images, technical description, licence or safety information).
3. Seller performance history (fulfilment rate, delivery times, disputes, verified reviews).
4. Aggregate user behaviour in relation to the offer (views, conversion, returns).
5. Recency of the offer and update frequency.
6. User preferences and history, where the user has consented to personalisation.

9.3. Remuneration and ranking. DDDIMO's organic search and browse results are not influenced, directly or indirectly, by any remuneration paid by a Seller. Neither the applicable fee rate, nor the Seller's plan, nor founding-member status, nor any seller programme, nor any additional payment changes an offer's position in organic results.

A plan buys a lower seller fee and additional tools. It does not buy visibility.

DDDIMO reserves the right to offer paid advertising placements in the form of promoted offers. In that case: (i) such offers are clearly and unambiguously labelled "Sponsored"; (ii) they are displayed in visually distinct areas, separate from organic results; (iii) they do not replace, reorder or demote organic results; and (iv) the advertiser and the main targeting parameters are identifiable under Article 26 DSA. As at this version, DDDIMO does not sell advertising placements.

9.4. Differentiated treatment (Article 7, P2B Regulation). DDDIMO does not sell its own offers in competition with Sellers. Should it do so, this clause will be amended, with the notice period in clause 25, to describe any differentiated treatment as regards data access, ranking, contractual conditions or features.

9.5. Recommender systems (Article 27 DSA). Where the Platform presents content using a recommender system, the main parameters are those in clause 9.2. You may disable behaviour-based personalisation in account settings and receive results ordered by non-personalised criteria.

10. USER CONTENT

10.1. Ownership. You retain full intellectual property ownership of the User Content you upload. DDDIMO acquires no ownership of any design, model, work or material.

10.2. Your representations and warranties. By uploading User Content, you represent and warrant that:

a) you hold the necessary rights, or valid written authorisation from the rights holder; b) the content does not infringe copyright, related rights, trade marks, designs, patents, trade secrets, personality rights, image rights or any other third-party right; c) the content is not unlawful, defamatory, misleading, obscene, discriminatory or an incitement to violence; d) the content contains no malicious code; e) you are entitled to grant the licences in clauses 10.3 and 10.4; f) the associated technical, safety and licensing information is true and complete; g) if you are a Professional Seller, you comply with all law applicable to your business, including tax, product safety and data protection obligations.

10.3. Licence granted to DDDIMO. You grant DDDIMO a non-exclusive, worldwide, royalty-free licence, transferable and sublicensable to DDDIMO's service providers, to store, host, reproduce, technically adapt, resize, convert formats, generate previews and renders, index, communicate to the public and display the User Content, solely in order to:

a) operate, maintain and secure the Platform; b) present the offer to users; c) promote the offer and the Platform on DDDIMO's own channels and in third-party advertising media; d) comply with legal obligations and respond to competent authorities.

10.4. Limits of the licence. The licence in clause 10.3 does not authorise DDDIMO to: (i) sell, license or distribute the Digital File to third parties outside the licensing mechanism set out in these Terms; (ii) manufacture or sell products derived from the User Content; (iii) use the User Content to train artificial intelligence models, its own or third parties', absent separate, specific and revocable consent given by you in account settings.

10.5. Duration and termination. The licence in clause 10.3 ends when the content is removed or the account is closed, except as regards: (i) copies held in backup systems for the technically necessary period; (ii) items whose retention is required by law; (iii) items necessary to perform and evidence Digital Licences already granted (clause 11.6).

10.6. No storage duty. DDDIMO does not provide a storage or archiving service. You must keep your own copies. DDDIMO is not liable for loss of uploaded data, without prejudice to clause 21.

11. LICENCES BETWEEN USERS

11.1. Secondary licence. The licence permitting a Buyer to use a Digital File is granted by the Seller to the Buyer. DDDIMO is not a party to that relationship, save as regards providing the technical mechanism, recording the licence and ensuring its traceability.

DDDIMO is never the licensor, assignor, publisher or supplier of a Digital File. No contractual document, invoice, receipt, transactional communication or interface element identifies it as such. As regards licensing, DDDIMO acts solely as the Seller's agent for presenting the offer, collecting acceptance, collecting the price and delivering the file technically. The heading of the licence text always identifies the Seller as licensor.

11.2. A licence, not ownership. Acquiring a Digital File gives the Buyer a limited, personal, non-transferable licence, revocable on breach, and not ownership of the underlying design or any intellectual property right in it. This is displayed prominently before each transaction is completed.

11.3. Licence types. The scope, permissions and limits of each licence type are set out in the Digital File Licence Terms, in the version in force at the date of acquisition:

• B1, Personal Use Licence: use and printing for personal, non-commercial purposes; selling physical products made from the file is prohibited; redistributing, reselling, sharing or sublicensing the file is prohibited.
• B2, Commercial Limited Licence: manufacture and sale of physical products up to the unit limit set by the Seller; the limit refers to physical units produced or sold, not to the number of downloads; redistributing, reselling, sharing or sublicensing the file is prohibited.
• B3, Commercial Unlimited Licence: manufacture and sale of physical products with no unit cap; redistributing, reselling, sharing or sublicensing the file is prohibited; claiming ownership of the original design is prohibited.
• Custom or enterprise licence: available by specific agreement between Seller and Buyer, where the Platform supports it.

11.4. Record and traceability. Each Digital Licence is uniquely and permanently linked to the Buyer, Seller, product, digital asset, licence type, order, transaction, purchase date and a License ID. DDDIMO retains a snapshot of the version of the licence terms accepted at checkout, so that historical purchases remain governed by the terms then accepted, even if those terms are later amended.

11.5. No guarantee of technical enforcement. DDDIMO provides traceability mechanisms, clear contractual rules and reporting and takedown channels. DDDIMO does not, and cannot, guarantee that Buyers will comply with licences, nor that downloaded files cannot technically be copied, redistributed or misused. A Buyer's breach of a licence is a breach of the contractual relationship between that Buyer and the Seller and does not give rise to liability on the part of DDDIMO. DDDIMO will nonetheless act on substantiated reports under clause 14.

11.6. Survival. Validly acquired Digital Licences remain in force even if the Seller closes their account, withdraws the offer or is suspended, unless the licence is revoked for the Buyer's breach or the withdrawal results from a reasoned decision concerning infringement of third-party rights.

11.7. Subsequent changes. A Seller may change the licence type applicable to future offers but may not retroactively change the terms of licences already acquired.

11.8. Default licence. Licence selection is mandatory and technically blocks publication under clause 8.2. Nevertheless, if for any reason, including catalogue migration, upload via programming interface or technical failure, a Digital File is made available without a licence expressly selected, the B1 Personal Use Licence, the most restrictive, applies by default. No Digital File is ever made available without a licence.

11.9. Withdrawal of offers. A Seller may withdraw an offer at any time. Withdrawal takes effect forty-eight hours after the request, during which period acquisitions in progress complete normally. Withdrawal does not affect, cancel or reduce licences already acquired, which survive under clause 11.6, nor prior transactions.

11.10. Seller support to Buyers. Sellers undertake to answer Buyers' questions about their offers within seven days, through the channels provided on the Platform. Repeated failure to do so is grounds for requesting that Cobuntu withhold payouts, refunding the Buyer at the Seller's expense and suspending the account.

11.11. Effect of a refund on the licence. A refund of the price of a Digital Licence, in whole or in part, on any ground and whether initiated by the Buyer, the Seller, DDDIMO, Cobuntu or a financial institution in a payment dispute, causes the immediate and automatic termination of the Digital Licence with effect from the date of the refund.

11.11.1. From that moment, the Buyer must cease all use of the Digital File and delete every copy in their possession or under their control, including backups, derivative files, sliced files and machine control files derived from it.

11.11.2. Retaining, using, reproducing, printing, manufacturing from, selling, sharing, transmitting or making available the Digital File, or any work derived from it, after the licence has terminated constitutes unlicensed use and infringement of the Seller's intellectual property rights, with the consequences set out in the Digital File Licence Terms and in applicable law.

11.11.3. DDDIMO retains, as evidence, the License ID, the timestamped record of download events, the exact version of the file downloaded and the record of the refund, under clause 19.9. These are made available to the Seller, on a substantiated request, for the exercise of their rights.

11.11.4. The Buyer acknowledges that termination of the licence does not depend on technical recovery of the file, which DDDIMO cannot ensure, and that disabling the download link is a containment measure, not restitution.

11.11.5. Obtaining a refund by false declaration, repeatedly requesting refunds for files actually downloaded and used, and systematic exploitation of refund mechanisms constitute abuse and are grounds for suspension or closure of the account under clause 14.7, without prejudice to civil and criminal liability.

12. DDDIMO'S INTELLECTUAL PROPERTY

12.1. The Platform, its code, databases, structure, interfaces, graphic elements and text, the DDDIMO name and logo, the signature "From File to Life" and other distinctive signs are owned by DDDIMO or its licensors and are protected by intellectual property rights.

12.2. You are granted a personal, limited, revocable, non-exclusive and non-transferable licence to access and use the Platform solely for the purposes set out in these Terms.

12.3. You may not copy, modify, decompile, reverse engineer, systematically extract content (scrape), replicate the Platform's structure, or use its content to build databases or train artificial intelligence models, without DDDIMO's written authorisation.

12.4. Third-party use of the DDDIMO brand is governed by the Brand Usage Guidelines.

13. PROHIBITED CONDUCT AND CONTENT

13.1. You may not use the Platform to upload, publish, sell, commission, promote, acquire or obtain, among others:

a) firearms, their essential components, receivers, auto-sear or full-auto conversion devices, suppressors, high-capacity magazines, and any file, instruction or technical data intended for their manufacture, including by additive manufacturing or computer numerical control. This prohibition is absolute and applies regardless of whether manufacture is lawful in your jurisdiction. Breach results in immediate removal, permanent account closure and referral to the competent authorities; b) other weapons, ammunition, explosives, explosives precursors and pyrotechnic materials; c) devices designed to circumvent security measures, access controls or digital rights management, and tools for unauthorised system access; d) any product, file, course, service or content classified at Level 4 of the Risk Classification Framework (clause 8.4 and document D34), including: i. Category III personal protective equipment, fall arrest systems, harnesses, carabiners, ropes and anchors, respiratory protection, lifejackets and buoyancy aids, hearing protection, welding gloves and equipment protecting against risks of death or irreversible injury; ii. medical devices within Regulation (EU) 2017/745, implants, splints, orthoses, prosthetic sockets, dental aligners, ventilation adapters and any item making a medical, therapeutic, diagnostic or rehabilitative claim; iii. safety-critical components of vehicles, bicycles, scooters and aircraft, braking, steering, suspension, power transmission, airworthiness structures; iv. components of gas, fuel or pressure installations, equipment within Directive 2014/68/EU or ATEX legislation; v. complete electrical articles intended for mains voltage connection and assembled by the Seller; vi. components of fire safety installations; vii. parts for climbing, mountaineering, load-lifting or sports equipment subject to loads bearing on people;

13.2. You must also not:

a) provide false information at registration, in an offer or in a declaration of rights ownership; b) manipulate reviews, ratings, download counts or performance metrics, including by posting, commissioning or purchasing fake reviews or reviews incentivised by reference to their sentiment; c) use bots, scripts or automated means to circumvent queues, purchase limits or verification measures; d) harass, threaten, impersonate or disclose third parties' personal data; e) circumvent fees contrary to clause 7.7; f) create accounts to circumvent suspension measures; g) repeatedly submit manifestly unfounded notices or complaints; h) overload, disrupt or compromise the integrity and security of the Platform; i) make generic or uncertified environmental claims about products, files, courses, services or events, including "eco", "green", "sustainable", "environmentally friendly", "biodegradable" or "carbon neutral", without adequate scientific evidence, independent third-party verification and information on the scope of the claim; present compliance with legal requirements as an advantage; or claim carbon neutrality based on offsetting (Directive (EU) 2024/825); j) display a partial price as the price of an offer, omitting mandatory service, processing or convenience charges from the total shown; k) in the case of an Event, direct ticket purchasers to an external ticketing or payment link, or collect the price of admission outside the Platform while presenting the Event as free of charge (clause 17.9).

13.3. The list of prohibited and restricted items is developed in the Prohibited and Restricted Items Policy, which may be updated to reflect legislative change, with the notice period in clause 25.

14. CONTENT MODERATION, NOTICE AND ACTION

14.1. No general monitoring obligation. DDDIMO is under no general obligation to monitor the content it hosts or actively to seek facts indicating illegality (Article 8 DSA). DDDIMO does, however, carry out voluntary automated and human checks.

14.2. Means used. Moderation uses: (i) automated systems detecting potentially unlawful content or content breaching these Terms, including file matching, image analysis and pattern detection; and (ii) human review, which is mandatory for all account suspension or termination decisions and for decisions subject to internal complaint.

14.3. Notice and action mechanism (Article 16 DSA). Any person or entity may report content they consider unlawful via the form at dddimo.com/report or at report@dddimo.com. A notice must contain: (i) a sufficiently substantiated explanation of why the content is unlawful; (ii) the exact electronic location of the content; (iii) the name and email address of the notifier, except where the content relates to offences under Articles 3 to 7 of Directive 2011/93/EU; (iv) a statement of good faith as to the accuracy of the information.

14.4. Handling. DDDIMO confirms receipt without delay, assesses the notice in a diligent, non-arbitrary and objective manner, and notifies the notifier of its decision, indicating the redress available. Where automated means are used, this is stated in the notification. Indicative assessment time: twenty-four to forty-eight hours for notices concerning manifestly illegal content or a safety risk, and a reasonable period otherwise.

14.4.1. Register of notices. DDDIMO maintains an internal register of all notices received, the measures taken and the relevant dates, as required by the DSA, retained for not less than five years and used as the basis for transparency reporting.

14.4.2. Electronic notice is sufficient. Notices are submitted solely electronically, via the form or address in clause 14.3. DDDIMO does not require postal mail, registered letter or paper documents as a condition of assessing a notice, including in copyright matters, such a requirement being incompatible with Article 16(1) DSA.

14.5. Measures. Depending on severity, DDDIMO may: remove or disable access to content; demote its visibility; suspend the offer; suspend or terminate the service; suspend or terminate the account; suspend payments to the Seller. Measures are applied in a diligent, objective and proportionate manner, with due regard to the rights and legitimate interests of all parties and to the fundamental rights enshrined in the Charter of Fundamental Rights of the European Union.

14.6. Statement of reasons (Article 17 DSA). Whenever DDDIMO applies any measure under clause 14.5 to a user, it will provide that user with a clear and specific statement setting out: the facts and circumstances relied on; whether automated means were used; the legal ground or contractual clause relied on; the territorial scope and duration of the measure; and the redress available, whether internal, out-of-court or judicial.

14.7. Anti-abuse policy (Article 23 DSA). After prior warning, DDDIMO will suspend for a reasonable period: (i) users who frequently provide manifestly illegal content; (ii) notifiers who frequently submit manifestly unfounded notices or complaints. In assessing this, DDDIMO considers the absolute number and proportion of instances, the gravity, the nature of the content and the apparent intent. The repeat-infringer policy for copyright is set out in clause 15 and Annex C.

14.8. Information on unlawful products (Article 32 DSA). On becoming aware that an unlawful product or service was offered through the Platform, DDDIMO will inform affected Buyers from the preceding six months, using available contact details or, failing that, by public notice, stating the identity of the Seller and the redress available.

15. THIRD-PARTY INTELLECTUAL PROPERTY

15.1. DDDIMO respects intellectual property rights and requires the same of its users. The notice, takedown, counter-notice and reinstatement procedure is set out in the Intellectual Property and Copyright Policy and the Reporting and Takedown Policy.

15.2. Repeat infringers. DDDIMO adopts and reasonably implements a policy of terminating the accounts of users who repeatedly infringe third-party intellectual property. Three substantiated notices not successfully challenged within twelve months result in permanent account closure.

15.3. Fan art and third-party IP. Publishing content inspired by third-party works, characters or brands requires the rights holder's authorisation. The absence of a commercial purpose is not, in itself, a ground of lawfulness. DDDIMO may remove such content on its own initiative.

16. COMPLAINTS, APPEALS AND OUT-OF-COURT DISPUTE RESOLUTION

16.1. Internal complaint-handling system (Article 20 DSA; Article 11 P2B Regulation). A user affected by a DDDIMO decision may lodge a complaint free of charge, for six months from notification of the decision, at appeals@dddimo.com. Complaints are handled within a reasonable period, in a non-discriminatory, diligent and non-arbitrary manner, under the supervision of appropriately qualified staff, and not solely by automated means. DDDIMO communicates a reasoned decision and reverses the measure where the complaint is upheld.

16.2. Out-of-court dispute settlement, moderation disputes (Article 21 DSA). A user who is not satisfied may refer the matter to an out-of-court dispute settlement body certified by the Digital Services Coordinator of a Member State. That body's decision is not binding on the parties. The list of certified bodies is available from the competent Digital Services Coordinator (in Portugal, ANACOM).

16.3. Consumer alternative dispute resolution (Article 18, Portuguese Law No. 144/2015). In a consumer dispute, the consumer may refer the matter to an alternative dispute resolution entity:

ADR entity: [TO COMPLETE] Website: [TO COMPLETE] Email: [TO COMPLETE]

Further information is available at the Portuguese Consumer Portal: https://www.consumidor.gov.pt

16.4. Portuguese Electronic Complaints Book. Consumers may submit a complaint through the Portuguese Electronic Complaints Book at https://www.livroreclamacoes.pt. DDDIMO responds within fifteen working days.

16.5. Mandatory arbitration in Portugal. Under Portuguese Law No. 63/2019 of 16 August, in consumer disputes with a value not exceeding EUR 5,000, the consumer may unilaterally elect arbitration or mediation before a competent ADR entity, and DDDIMO is bound by that election.

16.6. Mediators (Article 12, P2B Regulation). DDDIMO currently qualifies as a small enterprise and is therefore exempt from the obligation to designate mediators. Should DDDIMO cease to qualify, at least two mediators willing to mediate disputes with Professional Sellers will be identified in this clause, and Professional Sellers will be notified in accordance with clause 25.

16.7. Disputes between users, two layers. Disputes concerning a transaction are resolved between Buyer and Seller, who should first seek a direct settlement. Failing that, the following sequence applies, without overlap:

16.7.1. First layer, marketplace (DDDIMO). DDDIMO decides on: refund eligibility under clause 18; the scope and validity of licences; risk classification and conformity of offers; prohibited content; and enforcement of these Terms. DDDIMO communicates its determination to the Buyer, the Seller and, where it involves movement of funds, to Cobuntu.

16.7.2. Second layer, platform (Cobuntu). Cobuntu decides on: technical execution of refunds and payouts; timing and amounts; post-payout recovery; and platform operation. Cobuntu's decisions are governed by its Terms of Service.

16.7.3. Limits. Neither DDDIMO nor Cobuntu is a party to the dispute, and neither determines the parties' substantive legal rights. The determinations in clauses 16.7.1 and 16.7.2 are contractual policy decisions and do not prejudice recourse to the routes in clauses 16.2 to 16.5 or to the competent courts.

16.7.4. Payment disputes. A payment dispute raised with a financial institution is governed by card network rules and is outside DDDIMO's and Cobuntu's control. Using the internal procedure first is recommended: it is faster and incurs no additional charges.

17. PRICES, PAYMENTS, FEES AND TAXES

17.1. Price setting. Prices are set freely by the Seller, subject to the minimum sale price in clause 17.4.3. DDDIMO does not impose resale prices.

17.2. Total price. All prices are displayed clearly to the Buyer, including the total payable with all mandatory charges. Optional charges, import duties and shipping costs are itemised before the order is completed.

17.2.1. No buyer fee. DDDIMO charges the Buyer nothing. There is no service fee, booking fee, small-order fee, processing fee or convenience fee, in any category. The price displayed is the price payable, together with shipping and any applicable VAT, both shown before the order is placed.

17.3. Payment processing. Payments are collected by Cobuntu, as merchant of record, through Stripe. Cobuntu holds the amounts collected in escrow for the applicable refund window and transfers the net share due to the Seller to their connected Stripe account, on the terms and schedule set out in the Cobuntu Terms of Service.

17.3.1. DDDIMO does not collect, hold, transfer or refund funds. DDDIMO's financial role is limited to setting and disclosing the seller fee, determining refund eligibility under clause 18, communicating that determination to Cobuntu, and requesting the withholding of payouts in the cases set out in clause 17.5.

17.3.2. Neither DDDIMO nor Cobuntu stores full payment instrument data, which is handled solely by Stripe. Stripe's terms apply, as does the strong customer authentication required by applicable law.

17.3.3. Sellers must maintain a connected, verified Stripe account able to receive payouts. Without one, they may not publish offers priced above zero.

17.4. The seller fee

17.4.1. One fee, and nothing else. A single seller fee is deducted from each sale. It is expressed as a percentage of the item price and is set out in the Pricing Specification (P01) and the Fees, Payments and Payouts Policy (D11), by category and by plan.

Card processing is included in that percentage. DDDIMO and Cobuntu bear the cost of collecting the payment. No separate payment, processing, handling or administrative fee is charged to the Seller, and no further deduction is applied after the percentage.

This is a change from version 2.0 of these Terms, under which the processing fee was borne separately by the Seller. The present clause governs all sales completed on or after the effective date of this version.

17.4.2. Fee base. The seller fee is calculated on the price of the item alone.

Shipping is never part of the base. Amounts paid by the Buyer for delivery do not attract a seller fee, whoever arranges the carriage.

Taxes collected at checkout do not form part of the base.

17.4.3. Minimums.

Both are displayed on the plans page before a Seller subscribes, and in the Seller's dashboard. They are conditions of price within the meaning of Article 7 of Directive 2005/29/EC.

17.4.4. Seller plans. A plan is an optional subscription that lowers the seller fee and unlocks additional tools. A Seller may sell without one, on the Free plan, at the standard rates. Plan prices, billing frequencies and the fee rates attaching to each plan are set out in the Pricing Specification (P01).

17.4.5. Founding offer. A founding price is offered to a limited number of Sellers on each paid plan, announced on the plans page. The number available and the number remaining are displayed and must be accurate, and the offer closes when the places are taken.

The places are counted separately for each paid plan. Reaching the limit on one plan does not close the offer on the other.

Founding memberships are billed monthly and cannot be combined with yearly billing. The billing basis is stated explicitly at checkout. A founding member who switches to yearly billing leaves the founding offer and pays the standard yearly price; the Platform warns of that consequence before the switch is confirmed, and the change is not reversible by returning to monthly billing.

A founding member keeps the subscription price stated at subscription for two years from the date of first subscription, on the same plan and on monthly billing. At the end of that period the subscription moves to the standard price then in force, of which the member is notified at least sixty days in advance. There is no intermediate price step.

The yearly price published for each plan is available to every Seller and is not part of the founding offer. The founding benefit is the monthly rate without a yearly commitment, held for two years against a rising standard price, and not a discount below the published yearly rate.

The lock covers the subscription price only. It does not freeze the seller fee percentages, the feature set of the plan, or these Terms. Any change to those follows clause 25 and applies to everyone.

17.4.6. Which rate applies to a sale. The rate is the one in force on the Seller's plan at the moment the sale completes, not at the moment the offer was published. Upgrading applies the lower rate to sales completed from the upgrade onward; downgrading, or letting a plan lapse, applies the higher rate from that moment. Neither is applied retroactively to sales already completed.

The rate applicable to a listing is displayed before it is published, and again on every transaction statement.

17.4.7. Cancelling a plan. A Seller may cancel at any time, from account settings, through the same channel used to subscribe, without having to call, email or explain. Cancellation takes effect at the end of the current billing period; the Seller keeps the plan and its fee rate until then and is not charged again. The account then moves to the Free plan. Listings stay published and existing licences are unaffected. Only the fee rate changes.

The first subscription charge is refundable within seven days. Renewals are not refundable, but may be stopped at any time for the future. Where a Seller subscribes as a consumer rather than in the course of a business, the statutory right of withdrawal prevails over this paragraph.

17.4.8. Refunds and the processing cost. Where a Buyer is refunded, the seller fee on that sale is not retained, save where the refund results from the Seller's breach. The cost of collecting and reversing the payment is borne within the seller fee and is not re-charged to the Seller, and is never charged to the consumer. Clause 18.9 applies.

17.4.9. No sales threshold. The percentages applicable to a plan apply at every sales volume. There is no threshold above which a higher rate applies, on the Free plan or on any other. A Seller on the Free plan pays the published Free rate whether they bill fifty euros or fifty thousand in a month.

17.4.10. No other charges. There is no listing fee, no publication fee, no withdrawal fee and no payout fee. The optional plan is the only fixed cost, and the Free plan is free. If that ever changes, it is announced with the notice period in clause 25.

17.4.11. Donations and tips. Where a listing accepts a voluntary tip, the tip carries no seller fee. It reaches the Seller in full.

17.5. Payouts to Sellers. Payouts are executed by Cobuntu, in accordance with the schedule and conditions in its Terms of Service, including the expiry of the escrow window, the additional hold applicable to new sellers, the minimum payout amount and the frequency of processing.

17.5.1. Request to withhold. DDDIMO may request that Cobuntu withhold, in whole or in part, sums due to a Seller, and may block or hide that Seller's listings, where: there is a reasonable suspicion of fraud, infringement of third-party rights or breach of these Terms; a dispute, return, refund or payment dispute is pending; withholding is necessary to comply with a legal obligation, an authority's decision or a tax information request; the Seller fails to provide the information required by clause 17.7; or the Seller does not maintain the insurance required by clause 19.14. Execution of the withholding is a matter for Cobuntu under its Terms of Service.

17.5.2. Application of withheld sums. Sums withheld as a result of offers being removed for infringement of third-party rights or for illegality are earmarked for refunding the Buyers of those offers, on first request, for the applicable limitation period. The seller fee on transactions relating to offers removed for infringement of third-party rights is not refunded to the Seller.

17.5.3. Unpaid and disputed transactions. A transaction whose price is not in fact paid, or whose payment is reversed by a financial institution for fraud, misuse of a payment instrument or lack of authorisation, is cancelled and gives the Seller no right to receive payment. Clause 11.11 applies to the licence.

17.5.4. Post-payout recovery. Where a refund or payment dispute occurs after the corresponding amounts have been paid out to the Seller, the Seller remains responsible for the amount returned to the Buyer. Recovery is executed by Cobuntu under its Terms of Service, including by set-off against future payouts, debit of the connected account or creation of a negative balance. The Seller acknowledges that a payment dispute may be raised months after the transaction.

17.5.5. Flow of funds. Buyers and Sellers undertake not to make any payment relating to offers published on the Platform outside the Platform, and to provide accurate and current banking and tax information. Neither DDDIMO nor Cobuntu is liable for loss or non-receipt of a payout resulting from incorrect details provided by the Seller.

17.5.6. Transfer to a bank account. Transfer from the Seller's Stripe account to their bank account is a separate operation, governed by the payout schedule the Seller sets on their own Stripe account. Neither DDDIMO nor Cobuntu sets, changes or monitors that schedule, nor can either say when funds reached the bank.

17.6. Taxes. Save where the law provides otherwise or as set out in the Annexes, the Seller is solely responsible for determining, collecting, declaring and remitting taxes on its sales and for issuing legally required tax documents. Where the law makes DDDIMO a deemed supplier, marketplace facilitator or person liable for the tax, DDDIMO will comply with that obligation and inform the Seller.

17.6.1. VAT treatment. VAT on the seller fee and on plan subscriptions is assessed and remitted by Cobuntu under its Terms of Service. That VAT applies to the fee and the subscription, and does not change the tax treatment of the underlying sale, for which the Seller remains solely responsible.

17.6.2. Amounts paid out to Sellers are gross revenue; it is for the Seller to determine, declare and remit the tax due on the sale, according to their status and country of tax residence. A Seller's status is determined by the legal identity declared in their account. Neither DDDIMO nor Cobuntu is responsible for an incorrect rate resulting from a false or inaccurate declaration by the Seller.

17.6.3. Plan prices are shown excluding VAT where you are a business, and including VAT where you are a consumer. The applicable treatment is shown before you subscribe.

17.6.4. DDDIMO gives no tax advice. Sellers are responsible for the accuracy of their VAT registration details and for meeting their reporting obligations.

17.7. Seller information reporting (DAC7). Directive (EU) 2021/514, transposed in Portugal by Law No. 36/2023, requires the platform operator to collect, verify and report annually to the tax authorities information on Sellers and their transactions.

17.7.1. Sellers undertake to provide, on request, their name, address, tax identification number and issuing State, commercial registration number, date and place of birth for individuals, and details of the financial account into which they receive payment, and to notify any change to those details.

17.7.2. DDDIMO ensures that collection takes place during Seller onboarding and blocks publication of offers priced above zero until the details have been provided and verified.

17.7.3. Refusal to provide the information, after two requests, results in a request to Cobuntu to block payouts, the hiding of listings and may result in closure of the account.

17.7.4. Sellers receive a copy of the information reported about them to the authorities, within the statutory period.

17.7.5. The specific allocation of the reporting obligation between DDDIMO and Cobuntu, and the identity of the reporting platform operator, are set out in the Fees, Payments and Payouts Policy. As against the Seller, DDDIMO is answerable for the existence and operation of the collection process.

17.8. Legislative change. DDDIMO may adjust prices, fees and invoicing conditions as a result of legislative or tax changes, with the notice period in clause 25.

17.9. Events, admission and free events.

17.9.1. Where admission to an Event is offered free of charge, no seller fee is charged on the registration.

17.9.2. "Free of charge" means that the person registering pays nothing for admission. An Organiser may not present an Event as free while collecting the price of admission by any other means, whether before, during or after the Event.

17.9.3. The Event listing may not contain a link to an external ticketing service or payment page. All consideration for admission passes through the Platform.

17.9.4. Free registrations may be subject to a cap per plan, published on the plans page. Above that cap, a separate written agreement is required.

17.9.5. Breach of this clause is a serious breach of these Terms, amounts to circumvention of fees under clause 7.7, and is grounds for closure of the account.

18. REFUNDS, RIGHT OF WITHDRAWAL AND GUARANTEES

18.0. Structure

This clause distinguishes three grounds for a refund, with distinct and cumulative regimes:

Any clause, notice, product definition or platform configuration purporting to exclude grounds B or C is void and of no effect.

18.1. Responsibility

The right of withdrawal, the statutory guarantee of conformity and the obligation to return the price are obligations of the Seller. DDDIMO determines refund eligibility under this clause. Cobuntu technically executes the refund, under its Terms of Service.

18.2. GROUND A: WITHDRAWAL

18.2.1. Printed Products. A consumer resident in the European Union has fourteen days to withdraw from the contract without giving a reason, running from the date they acquire physical possession of the goods. The model withdrawal form is available on the Platform and in the Physical Product Terms. Statutory exceptions apply, in particular for goods made to the consumer's specifications or clearly personalised, and are flagged on the offer before purchase.

18.2.2. Digital Files, the rule. For digital content not supplied on a tangible medium:

18.2.3. Conditions for extinction. The right of withdrawal over a Digital File is extinguished only if, cumulatively:

a) the Buyer gave, before downloading, prior express consent to performance beginning before the fourteen-day period expires; b) the Buyer expressly acknowledged that performance beginning in this way causes the loss of the right of withdrawal; c) the Buyer received confirmation of that consent and acknowledgement on a durable medium, within a reasonable time after conclusion of the contract and at the latest when performance begins.

The exact wording of these three elements, how they are collected and the content of the confirmation are set out in Annex D, which forms an integral part of these Terms.

18.2.4. Consequence of failure. If any of the conditions in clause 18.2.3 is not met, the right of withdrawal survives for fourteen days from download, or for twelve months and fourteen days where the pre-contractual information was not provided, and the consumer bears no cost. DDDIMO acknowledges that extinction of the right depends on correct execution of the procedure and not on merely asserting that it exists.

18.2.5. The act of downloading. Downloading means the first effective transmission of the file to the Buyer's device, or first access to the content by any means allowing it to be retained. The event is recorded with date, time, Buyer identity, License ID and the exact file version, and retained under clause 19.9.

18.2.6. Courses. A consumer loses the right of withdrawal where the service has been fully performed with their prior express agreement and acknowledgement of that loss. For downloadable educational content, including e-books, clauses 18.2.2 to 18.2.5 apply. Specific conditions are set out in the Learning Terms.

18.2.7. Event Tickets. Under Article 16(l) of Directive 2011/83/EU there is no right of withdrawal for the provision of leisure services with a specified date or period of performance. Cancellation, postponement and refund conditions are set out in the Event Terms and bind the Organiser.

18.2.8. Discretionary refunds by the Seller. A Seller may, on its own initiative and at its own expense, grant a refund in situations not covered by this clause. Doing so is discretionary, sets no precedent and is not enforceable against DDDIMO.

18.2.9. Services. A consumer has fourteen days to withdraw from a contract for a Service, running from its conclusion.

Where the consumer has expressly requested that performance begin during that period, and has acknowledged that they lose the right of withdrawal once the Service is fully performed, the right is extinguished on full performance. Where the consumer withdraws after performance has begun but before it is complete, they pay an amount proportionate to what has been supplied, calculated on the agreed total price.

A Service made to the consumer's specifications or clearly personalised is excluded from the right of withdrawal under Article 16(c) of Directive 2011/83/EU. Most commissioned 3D work falls within this exception. The exclusion must be stated clearly on the offer before the commission is accepted; where it is not, the right survives in full.

18.3. GROUND B: NON-CONFORMITY

18.3.1. Regime. Printed Products, Digital Files, Courses and Services are subject to the conformity regime of Decree-Law No. 84/2021, transposing Directives (EU) 2019/770 and 2019/771. This regime is mandatory and applies regardless of whether the right of withdrawal has been extinguished.

18.3.2. Statutory guarantee for goods. In Portugal, consumers have a statutory guarantee of conformity of three years on movable goods, with a presumption of non-conformity in the first two years. In other Member States the minimum two-year period or the more favourable national period applies.

18.3.3. Non-conformity of a Digital File includes:

a) a file that is corrupt, unreadable, or does not open in the standard applications for the stated format; b) a file format different from that advertised; c) geometry, dimensions, number of parts or content materially different from the description, images or preview shown on the offer; d) absence of components, parts or variants expressly advertised; e) delivery of a file other than the one purchased; f) absence of the manufacturing information required by clause 19.11, where that absence prevents use of the file for the advertised purpose; g) removal of the offer as a result of infringement of third-party intellectual property rights.

18.3.4. Non-conformity does not include:

a) print failure or defect attributable to the Buyer's equipment, material, parameters or operation; b) incompatibility with equipment, materials or applications not stated on the offer as supported; c) difficulty of use, inexperience or lack of technical knowledge on the Buyer's part; d) an aesthetic result, finish or performance subjectively different from what was expected, where it conforms to the description; e) change of mind, mistaken purchase or non-use of the file; f) subsequent modification of the file by the Buyer; g) inability to access the file for reasons attributable to the Buyer.

18.3.5. Non-conformity of a Service means delivery that departs from the specification agreed under clause 8.7.4, including material, tolerance, finish, quantity or date. It does not include a result that conforms to the agreed specification but differs from the Buyer's unstated expectation.

18.3.6. Remedies. Where non-conformity is established, the Buyer is entitled, in the statutory order, to bringing the content or service into conformity, by delivery of a corrected file, replacement or re-performance; and, where that is impossible, disproportionate, not carried out within a reasonable time, or the non-conformity persists, to a price reduction or termination with a refund. Where the non-conformity is serious, termination may be immediate.

18.3.7. Time limits and burden of proof. Non-conformity may be raised within the applicable statutory periods, which are not shortened by the expiry of the withdrawal period or by downloading. Non-conformity appearing within the statutory presumption period is presumed to have existed at the time of supply.

18.3.8. Procedure. Requests are made through the channel stated on the offer or at support@dddimo.com, describing the problem and, where possible, providing supporting evidence. The Seller responds within seven days. If the Seller does not respond, or responds in a manifestly unfounded way, DDDIMO determines eligibility and instructs Cobuntu, at the Seller's expense.

18.4. GROUND C: ERROR, FAILURE AND FRAUD

18.4.1. A full refund is always granted, regardless of any time limit and of whether the file was downloaded, where there is:

a) a duplicate purchase of the same item by the same Buyer; b) an unauthorised, fraudulent payment, or one made with a misused payment instrument; c) non-delivery, the content was never made available, or the link never worked, for reasons not attributable to the Buyer; d) a manifest pricing error attributable to the offer or the Platform; e) permanent removal of the offer before the Buyer was able to access the content purchased; f) a determination by DDDIMO in a complaint procedure, or a decision of a competent authority.

18.4.2. In cases (b) and (c) the refund implies no judgement about the Buyer. In the remaining cases DDDIMO may require reasonable evidence.

18.5. Effect of a refund on the licence

Any refund, on any ground, terminates the Digital Licence immediately, with the effects set out in clause 11.11.

18.6. Alignment with the platform layer

18.6.1. The refund windows and technical mechanisms of the platform layer are configured so as to implement this clause. DDDIMO undertakes to keep that configuration aligned and not to publish Digital File offers while the configuration does not permit clause 18.2.2 to be applied.

18.6.2. Where, in a specific case, this clause and the actual behaviour of the platform layer diverge, and the Buyer is a consumer, the solution more favourable to the consumer prevails, without prejudice to rights of recourse between DDDIMO, the Seller and Cobuntu.

18.7. Abuse

Repeated and systematic refund requests for files actually downloaded, manifestly unfounded allegations of non-conformity, obtaining a refund by false declaration, and coordinated use of refund mechanisms to obtain content without paying constitute abuse, and are grounds for refusing further discretionary refunds and for suspension or closure of the account under clause 14.7, without prejudice to civil and criminal liability. The measures in this clause do not apply to the exercise of statutory consumer rights.

18.8. Product safety and recalls

Sellers undertake to cooperate with DDDIMO, Cobuntu and the authorities in any product recall or withdrawal, to bear the associated costs and to ensure the consumer receives adequate repair, replacement or refund, under Articles 35 and 36 GPSR, with no time limit.

18.9. Charges

A refund under clauses 18.2 to 18.4 is full and includes, where applicable, standard delivery costs. No processing charge, administrative fee or deduction of any kind is applied to the Buyer. Because card processing is borne within the seller fee under clause 17.4.1, there is no separate cost to allocate. Internal allocation between the Seller, DDDIMO and Cobuntu is governed by clause 17.4.8 and the Cobuntu Terms of Service, and is not enforceable against the consumer.

19. TRACEABILITY, ECONOMIC OPERATOR AND LIABILITY FOR DEFECTIVE PRODUCTS

19.1. Before allowing a Professional Seller to make offers available to consumers in the European Union, DDDIMO collects, under Article 30 DSA: name; address; telephone number and email address; a copy of an identity document or electronic identification; payment account details; commercial register number; and a self-certification that the Seller will only offer products or services complying with European Union law.

19.2. DDDIMO makes reasonable efforts to verify the reliability of the information collected, using official databases and online interfaces made available for that purpose.

19.3. Where information proves inaccurate, incomplete or out of date, DDDIMO requests correction and, absent a response, suspends the service until the position is regularised.

19.4. DDDIMO displays the Professional Seller's name, contact details and self-certification to consumers, and retains the information collected for the duration of the contractual relationship and for a maximum of six months thereafter, unless a longer statutory retention obligation applies.

19.5. Responsible economic operator in the Union, Printed Products. No Printed Product may be made available to consumers in the European Union unless there is an economic operator established in the Union responsible for the product, under Article 16 GPSR and Article 4(3) of Regulation (EU) 2019/1020. The Seller undertakes to identify that operator, which may be the Seller itself if established in the Union, an importer, an authorised representative or a contracted representative, and to ensure each offer displays the information required by Article 19 GPSR, including an image, the product type and identifiers, the identity and contact details of the manufacturer and of the responsible economic operator, and safety warnings and information in the required language.

This requirement admits no exception. Listing is technically blocked until the responsible economic operator is identified and verified, and is automatically suspended if the Seller loses that status or fails to keep it current.

19.6. Responsible economic operator in the Union, Digital Files. DDDIMO voluntarily extends the requirement in clause 19.5 to Digital Files intended to produce tangible objects. No Digital File may be made available to users in the European Union unless the Seller identifies a responsible economic operator established in the Union. This extension is not imposed by the GPSR, whose scope covers tangible products, but is required by the liability architecture of Directive (EU) 2024/2853, which treats digital manufacturing files as products in their own right.

19.7. Framework, Directive (EU) 2024/2853. With effect from 9 December 2026, the product liability regime extends to software and digital manufacturing files as products in their own right (Article 4(1) and (2), recital 16). Under Article 8(4) of that Directive, a provider of an online platform that is not an economic operator is liable only where both of the following are met: (i) the conditions of Article 6(3) DSA are fulfilled; and (ii) no economic operator established in the Union can be identified and the platform fails to identify one within one month. Clauses 7.8 to 7.10, 11.1, 19.5, 19.6 and 19.8 to 19.12 are designed to ensure that neither condition is met.

19.8. Identification procedure. Any injured person, or their representative, may ask DDDIMO to identify the economic operator responsible for a product or file, at identify@dddimo.com or via the form at dddimo.com/identify. DDDIMO responds within an internal target of seven days and in any event within the statutory one-month period, stating the name, legal form, physical address, contact details and registration number of the responsible economic operator or, failing that, of its own upstream supplier. Requests and responses are recorded with a timestamp.

19.9. Record retention. DDDIMO retains, for not less than ten years from the last date on which each version of each offer was made available, and twenty-five years in categories carrying a risk of slow-emerging personal injury: verified identification data for the Seller and the responsible economic operator, together with the verification history; the file version, with identifier, digital signature and timestamp, and the exact version associated with each download; a reproduction of the product page as displayed on the transaction date; the licence text and purchase flow in force on that date; conformity declarations and technical documentation collected; the specification agreed for a Service and the record of its acceptance; and identification requests and the responses given. Retention continues after a Seller's account is closed, on the basis of a legal obligation and the legitimate interest of defending legal claims, under Article 6(1)(c) and (f) GDPR, and is described in the Privacy Policy.

19.10. Technical documentation. The Seller undertakes to compile and retain, for the periods in clause 19.9, the technical documentation, risk assessment, declaration of conformity, material and manufacturing parameter specifications and batch or version records for each offer, and to deliver them to DDDIMO within ten days of a simple request. This obligation survives termination. For Level 2 and Level 3 offers, prior deposit of the essential documentation on the Platform is a condition of publication.

19.11. Mandatory information on Digital File offers. Each Digital File offer intended to produce a tangible object must display, under the Seller's responsibility: the identity and contact details of the creator and of the responsible economic operator in the Union; the specified material(s) and manufacturing parameters (filament or resin type, temperature, layer height, minimum infill, number of perimeters, print orientation and required post-processing); declared limits of use (maximum permissible load, temperature range, suitability for food contact, suitability for use by children, suitability for structural use); safety warnings; and the intended use. Absence or insufficiency of this information constitutes, under Article 7(2)(a) of Directive (EU) 2024/2853, an independent ground of defectiveness attributable to the Seller.

19.12. Negative warnings. Where applicable, the offer must carry an express and prominent warning that the product or the object resulting from the file is not suitable for structural or load-bearing use, for personal protective equipment, for food contact, for use by children or for any other undeclared purpose.

19.13. Versioning and provenance. Each version of each Digital File receives its own identifier, digital signature, date and time of availability and the identity of the publisher. For derivative works, the Seller undertakes to declare the derivation chain, identifying the source file, its author, the version and the date. The Seller acknowledges that substantially modifying a file makes them the manufacturer of the derivative product under Article 8(2) of Directive (EU) 2024/2853.

19.14. Product liability insurance. Sellers of Printed Products, of Digital Files intended to produce tangible objects, and Service Providers whose work produces tangible objects, undertake to take out and maintain product liability insurance on the terms, limits and conditions set out in document D34, with DDDIMO as co-insured or additional beneficiary and with the insurer waiving subrogation against DDDIMO. Evidence that the policy is in force is a condition of continued listing. Lapse, cancellation, reduction or non-renewal of cover triggers, in sequence: thirty days' advance warning; a block on new listings; hiding of existing listings; a request to Cobuntu to withhold payouts under clause 17.5.1; and suspension of the account.

19.15. Financial security. DDDIMO may require Sellers established outside the European Union, or Sellers of Level 2 or Level 3 offers, to provide financial security, or may request that Cobuntu withhold a percentage of payouts for a period proportionate to the risk profile, under document D34 and to the extent the platform layer permits. Where withholding is not technically possible, DDDIMO may make publication conditional on the provision of a standalone guarantee.

19.16. Accidents and incidents. The Seller undertakes to notify DDDIMO within twenty-four hours of any accident, safety incident, claim, notification from an authority or legal proceeding relating to a product, file or service made available through the Platform, and to cooperate fully in any recall, withdrawal, Safety Gate notification or request for evidence in proceedings. DDDIMO provides safety@dddimo.com for reports by Buyers and third parties.

20. SUSPENSION AND TERMINATION

20.1. Termination by you. You may terminate at any time under clause 6.4. Cancelling a paid plan is governed by clause 17.4.7 and does not close the account.

20.2. Restriction and suspension by DDDIMO. DDDIMO may restrict, suspend or make conditional your access to the Platform, in whole or in part, where: these Terms or the incorporated documents are breached; there is a reasonable suspicion of fraud, unlawfulness or infringement of third-party rights; information provided is false or is not corrected; there is a risk to the security of the Platform or of third parties; or this is required by law or by a decision of a competent authority.

20.3. Reasons and notice to Professional Sellers (Article 4, P2B Regulation). Where DDDIMO restricts or suspends the service to a Professional Seller, it will provide a statement of reasons on a durable medium before or at the time the measure takes effect. Where DDDIMO terminates the service, it will provide a statement of reasons with at least thirty days' notice. Notice is not required where DDDIMO is subject to a legal obligation preventing it, where it invokes an overriding reason of national law, or where the Seller has repeatedly breached these Terms.

20.4. Effects. Termination does not affect: orders in progress, which must be fulfilled; Digital Licences already granted, under clause 11.6; Services commissioned and not yet delivered; sums due; statutory retention obligations; or clauses which by their nature survive.

20.5. Discontinuation of the Platform. DDDIMO may discontinue the Platform or any of its features on reasonable notice, not less than thirty days for Professional Sellers, settling sums due, refunding the unused portion of any paid plan, and enabling users to export their data.

21. WARRANTIES, DISCLAIMERS AND LIMITATION OF LIABILITY

21.1. Provision of the Platform. DDDIMO will use reasonable efforts to keep the Platform available, functional and secure. DDDIMO does not warrant that the service will be uninterrupted, error-free or free of vulnerabilities, or that it will meet any specific commercial expectation.

21.2. No warranty as to third-party offers. DDDIMO gives no warranty as to the quality, safety, legality, conformity, accuracy, printability, fitness for purpose or value of any Printed Product, Digital File, Course, Service or Event, nor as to the standing, solvency or performance of any user.

21.3. Digital files. Digital Files are provided as is. DDDIMO does not warrant that a file is printable on any given technology, material or equipment, or that a print will exhibit any dimensional, mechanical, aesthetic or functional characteristic. Assessing a file's fitness for the intended purpose is the Buyer's responsibility.

21.4. Limitation of liability. To the maximum extent permitted by applicable law, DDDIMO's aggregate liability to a user for all events occurring in any twelve-month period, on any basis, will not exceed the greater of: (i) the total fees and subscription charges actually charged by DDDIMO to that user in the twelve months preceding the event; or (ii) one hundred euros (EUR 100).

21.5. Excluded losses. To the maximum extent permitted by applicable law, DDDIMO is not liable for loss of profit, loss of opportunity, loss of goodwill, loss of data, reputational harm, or any indirect or consequential loss.

21.6. Mandatory limits. The limitations in clauses 21.4 and 21.5 do not apply to: (i) loss caused by DDDIMO's wilful misconduct or gross negligence; (ii) death or personal injury; (iii) liability under product liability law; (iv) infringement of non-waivable consumer rights; (v) any other liability that mandatory applicable law does not permit to be excluded or limited. In Portugal, under Decree-Law No. 446/85 and Law No. 24/96, clauses excluding or limiting liability for harm to life, physical integrity or health, or for wilful misconduct or gross negligence, are void.

21.7. Not a seller. Nothing in these Terms, in the presentation of the Platform, in its visual identity or in the purchase flow is to be construed as DDDIMO holding itself out as the seller of goods or services offered by third parties.

21.8. Product liability, non-derogation. Liability under the defective products regime cannot be limited or excluded by contract as against the injured person, under Article 15 of Directive (EU) 2024/2853 and the national transposing regime. The limitations in clauses 21.4 and 21.5, the disclaimers in clauses 21.1 to 21.3, the indemnity in clause 22 and any acceptance of risk collected in the purchase flow have no effect whatsoever on the claim of a person injured by a defective product, whether or not that person contracted with DDDIMO or with the Seller. This clause states the legal position and does not restrict it.

21.9. Internal allocation. Clause 21.8 does not affect the right of recourse between economic operators, expressly preserved by Article 14 of Directive (EU) 2024/2853, nor the validity, as between DDDIMO and the Seller, of the indemnity, insurance, financial security and documentation obligations set out in these Terms and in document D34.

22. INDEMNITY

22.1. A user acting in the course of a business undertakes to indemnify, defend and hold harmless DDDIMO, its affiliates, directors, employees and service providers against any claim, action, loss, damage, fine, cost or reasonable expense, including legal fees, arising from: (i) breach of these Terms or the incorporated documents; (ii) infringement of third-party rights, in particular intellectual property; (iii) failure to comply with legal obligations applicable to their business, including tax, product safety and data protection; (iv) content they have uploaded; (v) products, files, courses, services or events they have offered; (vi) disputes with Buyers.

22.2. This obligation does not apply to consumers, to the extent mandatory applicable law does not permit it.

22.3. DDDIMO will notify the user of the claim, allow them to participate in the defence, and will not settle without their consent, which may not be unreasonably withheld.

23. PERSONAL DATA PROTECTION

23.1. Processing of personal data is governed by the Privacy Policy, which forms part of these Terms and satisfies Articles 13 and 14 of Regulation (EU) 2016/679 and applicable national law.

23.2. Allocation of roles. DDDIMO is an independent controller of account, browsing, security and moderation data. The Seller is an independent controller of the data it receives to fulfil an order. Where purposes and means are determined jointly, the joint controllership regime in Article 26 GDPR applies, with the essence of the arrangement made available to data subjects in the Privacy Policy.

23.3. Seller obligations. The Seller undertakes to: (i) process Buyers' data solely to fulfil the order, comply with legal obligations and provide after-sales support; (ii) not use that data for marketing without separate consent; (iii) not transfer it to third parties without a legal basis; (iv) honour data subject rights requests; (v) notify DDDIMO of any data breach involving data obtained through the Platform within twenty-four hours.

23.4. Where DDDIMO processes data on the Seller's behalf, the Data Processing Agreement available on the Platform applies.

23.5. Cookies. The use of cookies and equivalent technologies is governed by the Cookie Policy and requires prior consent under Portuguese Law No. 41/2004.

24. ACCESSIBILITY AND ARTIFICIAL INTELLIGENCE FEATURES

24.1. Accessibility. DDDIMO seeks to ensure that the Platform meets the accessibility requirements of Directive (EU) 2019/882, transposed by Portuguese Decree-Law No. 82/2022, taking as its reference standard EN 301 549 and the Web Content Accessibility Guidelines 2.1, level AA. A description of how the service meets those requirements is set out in the Accessibility Statement, available at dddimo.com/accessibility and kept up to date throughout the life of the service.

24.2. Interaction with artificial intelligence systems (Article 50, Regulation (EU) 2024/1689). Where you interact with an artificial intelligence system on the Platform, including conversational assistants, description generation, image generation or enhancement, or generative search, this is clearly indicated at the point of interaction.

24.3. Synthetic content. Text, image, audio or video content generated or manipulated by DDDIMO's artificial intelligence systems is marked in a machine-readable format and identified as artificially generated.

24.4. User-generated content. Sellers undertake to declare, during upload, whether a Digital File was generated, in whole or in substantial part, by a generative artificial intelligence system. That information is displayed on the offer. The applicable rules are set out in the AI-Generated Content Policy.

25. CHANGES TO THESE TERMS

25.1. DDDIMO may amend these Terms and the incorporated documents, in particular to reflect legislative change, decisions of authorities, developments in the Platform or changes to its business model.

25.2. Notice. Significant changes are communicated on a durable medium, with minimum notice of:

• fifteen days for Professional Sellers, or longer where the change requires technical or commercial adaptations (Article 3(2), P2B Regulation);
• thirty days for changes that materially increase a Professional Seller's obligations or materially reduce their rights, including any increase in a seller fee percentage or in a plan price;
• fifteen days for all other users.

25.3. Right to terminate. You may terminate the contractual relationship, at no cost, before the notice period expires. Continued use of the Platform after a change takes effect constitutes acceptance. Where the change is an increase in a plan price, you may cancel the plan free of charge before it takes effect, and no increase applies to a founding member within their two-year lock.

25.4. No retroactivity. Changes do not apply retroactively to completed transactions, to orders already placed, to Services already commissioned or to Digital Licences already acquired, unless they are exclusively favourable to the user or required by law. Changes that do not respect the notice period in clause 25.2 are of no effect as against Professional Sellers.

25.5. Immediate changes. Changes required by law, by a decision of a competent authority, or by the need to respond to a security risk or imminent unlawfulness may take immediate effect and will be communicated as soon as possible.

25.6. Version archive. DDDIMO maintains a version history of these Terms, stating the effective date of each version.

26. GOVERNING LAW AND JURISDICTION

26.1. Governing law. These Terms are governed by Portuguese law, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods.

26.2. Consumers. The choice of law in clause 26.1 does not deprive a consumer of the protection afforded by the mandatory provisions of the law of their country of habitual residence, under Article 6 of Regulation (EC) No 593/2008.

26.3. Jurisdiction. The courts of [TO COMPLETE], Portugal, have exclusive jurisdiction over disputes arising from these Terms. This clause does not apply to consumers, who may always sue and be sued in the courts of their domicile, under Regulation (EU) No 1215/2012 and applicable national rules.

26.4. Jurisdictional Annexes. Users resident in the jurisdictions identified in the Annexes are subject to those Annexes, which prevail over the general terms.

27. FINAL PROVISIONS

27.1. Assignment. You may not assign your contractual position without DDDIMO's written agreement. DDDIMO may assign its position in the context of a corporate reorganisation, merger, demerger or business transfer, on notice to you, and you may terminate if the assignment prejudices you.

27.2. Severability. The invalidity or unenforceability of any clause does not affect the remainder, which continues in force; the invalid clause is to be replaced by one that comes as close as the law permits to the intended economic effect.

27.3. No waiver. Tolerance or failure to exercise a right is not a waiver of that right and does not prevent its later exercise.

27.4. Force majeure. Neither party is liable for failure to perform caused by events outside its reasonable control and not attributable to it.

27.5. Survival. Clauses 10.5, 11, 12, 17.5 to 17.7, 21, 22, 23, 26 and 27 survive termination for the period permitted by law, together with all clauses which by their nature should survive.

27.6. Entire agreement. These Terms and the incorporated documents constitute the entire agreement between the parties on their subject matter and supersede prior understandings.

27.7. Language. These Terms are provided in Portuguese and English. In the event of a discrepancy in interpretation, the Portuguese version prevails, without prejudice to a consumer's right to rely on the version in the language in which the contract was presented to them.

27.8. Formation of the contract. The contract is concluded through the following technical steps: selecting the offer; adding it to the basket; entering billing and delivery details; selecting a payment method; reviewing an order summary with the ability to identify and correct input errors; confirming the order; and receiving an electronic acknowledgement of receipt. The contract is filed by DDDIMO and remains accessible to you in your account area. The languages available for concluding the contract are Portuguese and English.

ANNEX A: PROVISIONS APPLICABLE TO CONSUMERS IN THE EUROPEAN UNION AND THE EEA

A.1. Nothing in these Terms affects rights conferred on consumers on a mandatory basis by the consumer protection law of a Member State.

A.2. The following do not apply to consumers: the indemnity in clause 22; the limitations in clauses 21.4 and 21.5, to the extent the law does not permit them; and any mandatory arbitration or class action waiver.

A.3. Consumers may bring representative actions under Directive (EU) 2020/1828.

A.4. Clauses 16.2 to 16.5, 18 and 19 apply in full.

A.5. Obligations in force since 27 September 2026, Directive (EU) 2024/825. The following are implemented on the Platform and reflected in the Physical Product Terms: (i) the harmonised notice on the statutory guarantee of conformity, using the template in Implementing Regulation (EU) 2025/1960; (ii) information on the period during which software updates will be provided for goods with digital elements and for digital content; (iii) information on reparability and spare part availability; (iv) lower-impact delivery options; and (v) the prohibition of generic, uncertified environmental claims in offers.

A.6. Liability for defective products, Directive (EU) 2024/2853. The new regime applies to products placed on the market from 9 December 2026 and covers software and digital manufacturing files as products in their own right. Clauses 7.8 to 7.10, 8.4 to 8.7, 11.1, 13.1(d), 19.5 to 19.16 and 21.8 and 21.9 apply in full, together with document D34.

The regime is characterised by: strict liability, independent of fault; removal of the previous EUR 500 threshold; compensability of medically recognised psychological harm and of destruction or corruption of data not used professionally; presumptions of defectiveness and of causation in favour of the claimant, in particular where evidence is not disclosed, mandatory safety requirements are breached, or proof involves excessive technical difficulty; joint and several liability among responsible operators; a three-year limitation period and a ten-year longstop, extended to twenty-five years for slow-emerging injuries.

A.7. Status of transposition in Portugal. As at this version no transposing instrument has been published; Decree-Law No. 383/89 of 6 November remains in force. DDDIMO plans its compliance against the text of the Directive rather than against national law in force, given the full harmonisation regime in its Article 3. These Terms will be revised once the transposing instrument is published, in particular as regards any derogation from the development risk defence (Article 18) and the procedural regime for disclosure of evidence (Article 9).

A.8. 8 December 2026 milestone. DDDIMO will make a dated, reliably timestamped record of the full state of the catalogue on 8 December 2026, in order to demonstrate which offers were placed on the market before that date, under the previous regime, and which after it, under Directive (EU) 2024/2853. Sellers acknowledge that republishing, versioning or updating an offer after that date brings it within the new regime.

A.9. Seller plan subscriptions. Where a Seller subscribes to a paid plan as a consumer rather than in the course of a business:

a) the total price, the billing frequency, the minimum duration and the means of cancellation are displayed before the subscription is confirmed, under Article 6 of Directive 2011/83/EU; b) the statutory fourteen-day right of withdrawal applies to the subscription and prevails over the seven-day refund in clause 17.4.7; c) cancellation is available through the same channel used to subscribe, with no obligation to call, write or give a reason; d) a reminder is sent before any annual renewal and before any price change takes effect; e) where a founding price ends, notice is given at least sixty days in advance and the Seller may cancel free of charge before the new price applies.

ANNEX B: PROVISIONS APPLICABLE TO USERS IN BRAZIL

B.1. Precedence. In consumer relationships governed by Law No. 8,078/1990 (Consumer Protection Code, "CDC"), this Annex prevails over the general terms.

B.2. Jurisdiction and arbitration. Clause 26.3 does not apply. The consumer may sue in the courts of their own domicile (Article 101, I, CDC). Any mandatory arbitration clause does not apply (Article 51, VII, CDC).

B.3. Limitation of liability. Clauses 21.4 and 21.5 do not apply to the extent they would exclude or reduce liability for defects (Article 51, I, CDC).

B.4. Marketplace liability. DDDIMO acknowledges that, following the Brazilian Supreme Federal Court's ruling of 26 June 2025 (Themes 987 and 533) and settled Superior Court of Justice case law, providers acting as marketplaces are civilly liable under the Consumer Protection Code. Nothing in this document displaces that liability. DDDIMO's right of recourse against the Seller is governed by the Seller Terms.

B.5. Right of withdrawal. The consumer has seven calendar days from contracting or from receipt of the product to withdraw, without giving a reason and at no cost, including return shipping (Article 49 CDC). Withdrawal is exercised through the same channel used to contract, with immediate confirmation, automatic termination of ancillary contracts and immediate notice to the card issuer for reversal.

B.5.1. This right applies equally to digital files, courses, services and digital content, including files already downloaded. The exception in Article 16(m) of Directive 2011/83/EU does not apply in Brazil, and the extinction of the right of withdrawal in clause 18.2.2 is not enforceable against a Brazilian consumer. Any clause to the contrary is void under Article 51, items I and IV, CDC.

B.5.2. Effects. Exercising the right of withdrawal over a digital file causes, under clause 11.11: immediate termination of the licence; the obligation to cease all use and delete every copy, including derivatives; and the characterisation as unlicensed use of any subsequent retention, printing, manufacture, sale or sharing. DDDIMO retains the License ID, the timestamped download record, the exact file version and the record of the reversal, and makes them available to the Seller, on a substantiated request, for the exercise of their rights.

B.5.3. Prior information. Digital file offers directed at consumers in Brazil state, before purchase, that exercising the right of withdrawal terminates the licence and requires deletion of all copies.

B.5.4. Abuse. Repeated exercise of the right of withdrawal over files actually downloaded and used, where it shows an intention to obtain content without paying, constitutes abuse of right under Article 187 of the Brazilian Civil Code, and is grounds for suspension or closure of the account, without prejudice to the refund due in each specific case and without prejudice to the regular exercise of the right.

B.5.5. Application of clause 18.3. The regime for defects in products and services under Articles 18 to 26 CDC applies cumulatively and independently of the right of withdrawal.

B.5.6. Subscriptions. The seven-day right of withdrawal applies to a paid plan subscription, from the date of contracting. Cancellation is available through the same channel used to subscribe, and is confirmed immediately.

B.6. Complaint periods. Thirty days for non-durable and ninety days for durable products and services, from actual delivery (Article 26 CDC); thirty days for the supplier to cure a defect (Article 18, §1); a five-year limitation period for harm caused by a product (Article 27). These periods may not be shortened.

B.7. Mandatory information. Each offer displays, prominently and before contracting, the items required by Article 2 of Decree No. 7,962/2013, including the Seller's business name and registration number, physical and electronic address, essential characteristics, health and safety risks, an itemisation of all additional costs, and the full conditions of the offer.

B.8. Customer service. DDDIMO responds to consumers' electronic requests within five days, under Article 4, VII, of Decree No. 7,962/2013.

B.9. Content removal. Consistent with the Supreme Federal Court's ruling on Article 19 of Law No. 12,965/2014, DDDIMO removes unlawful content on receipt of a substantiated extrajudicial notice, without requiring a court order, save for offences against honour. DDDIMO maintains a dedicated, widely publicised complaints channel, publishes annual transparency reports and provides a procedure with the right to be heard and to appeal.

B.10. Immediate takedown content. DDDIMO removes immediately, without notice, content relating to terrorism, child sexual exploitation, incitement to suicide, human trafficking, discrimination and anti-democratic acts.

B.11. Logs. DDDIMO retains application access logs for six months (Article 15, Law No. 12,965/2014), disclosing them on court order (Article 22).

B.12. Minors. The obligations of Law No. 15,211/2025, in force since 17 March 2026, apply, including reliable age verification mechanisms, self-declaration alone is prohibited, privacy and safety settings by default, parental supervision tools, and a prohibition on profiling-based advertising to minors.

B.13. Data protection. Law No. 13,709/2018 (LGPD) applies. DDDIMO identifies a data protection officer and their contact details in the Privacy Policy. International transfers from Brazil are made under the ANPD Standard Contractual Clauses (Resolution CD/ANPD No. 19/2024).

B.14. Legal representative in Brazil. DDDIMO's legal representative in Brazil, appointed as required by the Supreme Federal Court's ruling, by Law No. 15,211/2025 and by the LGPD for foreign controllers, is:

Name: [TO COMPLETE] Address: [TO COMPLETE] Email: [TO COMPLETE]

B.15. Taxation. Under Complementary Law No. 214/2025, a digital platform that controls collection, payment, the setting of terms and conditions, or delivery is liable for IBS and CBS, in full and by substitution where the supplier is resident abroad, and jointly where a domestic supplier fails to issue a tax document. The platform layer is responsible for registration in the IBS/CBS register and for the resulting reporting and split-payment obligations. Sellers undertake to provide the tax information required for that purpose.

B.16. Events. The Organiser is responsible for compliance with Law No. 12,933/2013 (half-price tickets) and the corresponding document checks.

ANNEX C: PROVISIONS APPLICABLE TO USERS IN THE UNITED STATES

C.1. Designated agent (DMCA). Under 17 U.S.C. § 512(c)(2), DDDIMO designates the following agent to receive notifications of claimed copyright infringement:

Name: [TO COMPLETE] Address: [TO COMPLETE] Telephone: [TO COMPLETE] Email: dmca@dddimo.com

C.2. Notice and counter-notice. The procedure follows the elements of § 512(c)(3). An affected user may submit a counter-notice under § 512(g), with content restored between ten and fourteen business days unless the notifier files suit. Material misrepresentation gives rise to liability under § 512(f).

C.3. Repeat infringers. Clause 15.2 applies.

C.4. INFORM Consumers Act. DDDIMO collects and verifies, within ten days, the identity, bank account, tax identification number, email address and telephone number of every high-volume Seller, with annual recertification, and discloses to Buyers the full name, physical address and direct contact of Sellers reaching USD 20,000 in annual revenue. Each offer displays a clearly visible mechanism for reporting suspicious activity. Failure to provide the required information results in account suspension.

C.5. Reviews and testimonials. 16 CFR Part 465 applies in full. The following are prohibited: fake or AI-generated reviews; reviews by persons with undisclosed material connections; buying or selling reviews; incentives conditioned on the sentiment of a review; selective suppression of negative reviews; and purchased indicators of social influence.

C.6. Digital goods, licence disclosure. In compliance with California law (AB 2426), the Platform does not use the words "buy", "purchase" or equivalents in relation to Digital Files and Courses without clearly and conspicuously disclosing, before the transaction is completed, that the Buyer acquires a revocable licence and not ownership, with a link to the licence terms and affirmative consent.

C.7. Taxes. DDDIMO acts as a marketplace facilitator in states where the law so provides, collecting and remitting sales tax. Sellers undertake to provide the classification and exemption information required, and the applicable Form W-9 or W-8BEN, failing which statutory backup withholding applies. DDDIMO issues Forms 1099-K as required by law in force.

C.8. Weapons files. The prohibition in clause 13.1(a) is absolute. DDDIMO observes the Third Circuit's decision in Defense Distributed v. Attorney General of New Jersey (167 F.4th 65, 12 February 2026), as well as the laws of New Jersey, New York, Washington and other states criminalising the distribution of digital instructions for the three-dimensional printing of firearms, and cooperates with the competent authorities.

C.9. Binding individual arbitration and class action waiver.

C.9.1. Scope. This clause applies only to users resident or domiciled in the United States. It does not apply to consumers resident in the European Union, the European Economic Area, the United Kingdom or Brazil, to whom clause 26 and Annexes A and B apply.

C.9.2. Informal pre-dispute negotiation. Before commencing any proceeding, the party raising a dispute must send a Notice of Dispute to arbitration@dddimo.com, identifying themselves, describing the dispute and stating the relief sought. The parties then have sixty days to resolve it informally. This step is a condition precedent and limitation periods are tolled while it runs.

C.9.3. Arbitration. If the dispute is not resolved, it will be submitted to binding individual arbitration under the Federal Arbitration Act, administered by [AAA / JAMS] under its applicable consumer rules, including its Mass Arbitration Supplementary Rules. Proceedings are conducted on the papers or by videoconference unless the arbitrator directs otherwise; if an in-person hearing is held, it takes place in the district where the user resides.

C.9.4. Class action waiver. The parties waive trial by jury and waive bringing, joining or participating in any class, collective, consolidated, representative or private attorney general action. The arbitrator may not consolidate different users' claims or adjudicate on a class basis. If this waiver is held invalid as to a particular claim, that claim, and only that claim, will be determined in court, with arbitration continuing for the remainder.

C.9.5. Right to opt out. You may opt out of this clause by written notice to arbitration@dddimo.com within thirty days of first accepting these Terms, stating your name, the email address on the account and an unambiguous statement that you opt out. Opting out does not affect any other right or obligation and may not be the basis for any adverse action against you.

C.9.6. Exceptions. Notwithstanding this clause, either party may: (i) bring an action in a competent small claims court, provided it remains individual; (ii) seek injunctive relief in court to protect intellectual property rights; and (iii) seek public injunctive relief in the California courts, which is not subject to arbitration.

C.9.7. Mass arbitration. Where twenty-five or more substantially similar claims are filed by or with the coordination of the same counsel, the administrator's batching protocol applies: claims are organised into batches, each decided by one arbitrator, with those decisions guiding resolution of the remainder. The parties undertake to cooperate in good faith with that process.

C.9.8. Costs. Administrative costs and arbitrator fees are borne in accordance with the administrator's rules. Where the user is a consumer, DDDIMO bears the portion of costs exceeding what the user would bear in an equivalent court action.

C.9.9. Delegation. Questions as to the existence, validity, scope and enforceability of this clause are for the arbitrator, except those concerning the waiver in clause C.9.4, which are for a court of competent jurisdiction.

C.9.10. Changes. Amendments to this clause take effect only for disputes arising after they come into force and give rise to a fresh right to opt out under clause C.9.5.

C.10. Privacy. State privacy laws apply, including the CCPA/CPRA as in force. Rights of access, deletion, correction, portability, opt-out of sale or sharing of personal information and limitation of the use of sensitive personal information, together with recognition of universal opt-out signals, are described in the corresponding annex to the Privacy Policy.

C.11. Automatic renewal of seller plans. Paid plans renew automatically until cancelled. The Restore Online Shoppers' Confidence Act, as amended, and state automatic renewal laws apply, including California AB 2863. Accordingly:

a) the renewal terms, the recurring charge, the renewal frequency and the means of cancellation are disclosed clearly and conspicuously, immediately adjacent to the consent mechanism, before any charge is made; b) affirmative consent to the recurring charge is obtained and recorded separately from acceptance of these Terms; c) an acknowledgement containing the renewal terms and the cancellation procedure is sent after enrolment, in a form the subscriber can retain; d) cancellation is available online, through the same medium used to subscribe, in a manner at least as simple as enrolment, with no retention call, no chat requirement and no additional step not present at enrolment; e) where a founding or introductory price ends and a higher price begins, notice is given at least sixty days before the first charge at the higher price, stating the new amount, the date of the first such charge and how to cancel; f) an annual reminder is sent for any plan billed less frequently than monthly.

ANNEX D: DIGITAL CONTENT CONSENT MECHANICS

This Annex forms an integral part of these Terms and implements clause 18.2.3. The wording is binding: changing its substance requires legal review and a new version of these Terms.

D.1. Principle

The right of withdrawal over digital content is extinguished only if all three elements of Article 16(m) of Directive 2011/83/EU are collected and retained. If any one is missing or defectively collected, the right survives intact and the consumer bears no cost. Asserting extinction in the Terms is not enough: it is the procedure that produces it.

D.2. Mandatory sequence

D.3. Step 2: checkbox wording

Two separate checkboxes, both unticked by default, both mandatory to complete the purchase. They may not be merged into one, nor combined with general acceptance of the Terms.

Notice displayed immediately above the checkboxes, visually prominent:

D.4. Step 3: confirmation on a durable medium

Sent by email immediately after payment, in a message the Buyer can retain and transfer. It must contain at least:

• the Seller's identity, including legal name and contact details;
• identification of the file purchased and its version;
• the licence type purchased and a summary of its permissions and restrictions;
• the License ID;
• the price paid and the date;
• verbatim reproduction of both texts in clause D.3, stating that they were accepted, with the date and time of acceptance;
• a statement that the right of withdrawal is extinguished on first download and that rights for non-conformity remain;
• a link to the refund procedure and to the support channel.

D.5. Step 4: recording the download

On first download the following is recorded and retained under clause 19.9: the Buyer's identity; the License ID; the identifier and digital signature of the exact file version; date and time with time zone; and IP address.

D.6. Evidence to retain

For each purchase, and for the periods in clause 19.9: the version of the Terms and licence in force on the date; a reproduction of the purchase interface as displayed; the record of both acceptances with date and time; a copy of the confirmation sent; and the record of first download.

D.7. Where this procedure does not apply

Consumers in Brazil, the seven-day right of withdrawal survives, under Annex B, point B.5. The interface must show them the notice in clause B.5.3 instead of the wording in clause D.3.

Free offers, not applicable, as there is no price.

Files included in a Course, applies to the downloadable component, under clause 18.2.6.

Services, clause 18.2.9 applies instead, with its own consent and acknowledgement collected before work begins.

D.8. Platform requirement

Until the platform layer supports collection of all three elements and configuration of the refund window under clause 18.2.2, no Digital File offers priced above zero are published. DDDIMO does not assert an extinction of the right of withdrawal that has not been validly produced.
