Terms of Use

Version: August 2026 — DRAFT, legal review pending

Section 1: Scope, Provider, Definitions

1. The provider of the platform and your contracting partner is: 3 Layer Prototyping, owner: Valentin Lenz, Torfstraße 19, 13353 Berlin, Germany (“Provider” or “CNC Base”). Contact: info@cncbase.de.

2. These Terms of Use (“Terms”) govern the use of the websites cncbase.de, cncbase.tools, fingerjointbox.com and livinghingegenerator.com (together the “Platform”), including the community features, the online tools and the paid services. fingerjointbox.com and livinghingegenerator.com are offerings of the same Provider and use the Platform’s shared account, quota and payment system.

3. A “Consumer” is any natural person who enters into a legal transaction for purposes that are predominantly outside their trade, business or profession (Sec. 13 of the German Civil Code, BGB). An “Entrepreneur” is a natural or legal person or a partnership with legal capacity who, when entering into a legal transaction, acts in the exercise of their trade, business or profession (Sec. 14 BGB).

4. Definitions: “Content” means texts, images, project descriptions, comments, CAD/CAM files, G-code, drawings and other files posted by users (community uploads). “Tool Files” means files (e.g. DXF, SVG, STEP, STL) generated by the Platform’s tools based on your inputs. “Plans” means the paid subscriptions described in Section 11; “Tool Download” and “Quota” are explained in Section 11.

5. Deviating or supplementary terms and conditions of the user shall not apply unless the Provider expressly agrees to them in text form.

6. These Terms are provided in German and English. The English version is provided for convenience; the German version prevails (Section 21(4)).

Section 2: Platform Services (Overview)

1. Community: The Platform enables the discovery, sharing, commenting and downloading of CNC-related projects and files (e.g. cutting files, technical drawings, project images, instructions) as well as interaction within the community (see Sections 4–10).

2. Tools: The Platform provides parametric generators (“Tools”) that create manufacturing files based on your inputs. There are free tools (subject to a daily export limit, Section 11(8)) and paid services (file generation after a single purchase or under a Plan, see Section 11).

3. The Provider strives for high availability but does not owe uninterrupted accessibility. Maintenance, updates or disruptions may lead to temporary restrictions.

4. The Provider continuously develops the Platform and may change, label as beta, restructure or discontinue individual tools, features or file formats. If such a change affects material services of an active paid Plan, Section 13(6) and Section 20 apply.

5. User content (e.g. project descriptions and comments) may be translated automatically by machine (German ↔ English). Machine-translated content is labelled as such; the original version remains available.

Section 3: Registration, User Account, One Account for All Sites

1. When creating an account, the mandatory information requested during the registration process must be provided truthfully (in particular email address, username, password, first name, last name, date of birth and country).

2. Access credentials must be kept confidential and protected against access by third parties. Users are obligated to inform the Provider without undue delay if unauthorized use is suspected.

3. A user account is personal and may not be transferred or made available to third parties without the Provider’s consent — including for the shared use of quotas (Section 11, Section 15(5)).

4. One account is valid on all sites of the Platform: anyone who registers on one of the sites can sign in on all sites with the same credentials. Sign-in takes place separately on each domain. The email address is the account’s cross-site key; registering with an already registered email address does not create a second account. Password changes take effect on all sites.

5. Confirmation of the email address (verification) is required for signing in and for purchases while signed in. Purchases made without an account (guest purchases, Section 11(4)) are automatically assigned to an account registered and verified later with the same email address.

6. Minors may only use paid services with the consent of their legal guardians.

Section 4: Community Rules and User Obligations

1. Users agree to maintain a respectful tone and shall refrain in particular from:

  • insulting, discriminatory, harassing, violence-glorifying or otherwise unlawful content,
  • spam, misleading statements, fraud or attempts at manipulation,
  • circumventing technical protective measures (e.g. rate limits) or unauthorized scraping in a harmful manner.

2. Users may not post content that infringes third-party rights (e.g. copyright, trademark, design or personality rights) or discloses trade or business secrets.

3. CNC work can be dangerous. Users are obligated to publish content only in a way that does not encourage dangerous behavior or provide obviously unsafe recommendations (e.g. lack of protective measures). This does not replace the user’s own risk assessment.

Section 5: Uploads — Responsibility, Review Obligations and Moderation

1. Users are solely responsible for all content they post.

2. Users warrant that they hold all rights necessary to upload and publish the content, and that the content is free of third-party rights or that corresponding usage rights/licenses exist.

3. The Provider is entitled to review, moderate, block or delete content before or after publication, in particular in cases of suspected infringement, violation of these Terms, or to maintain platform quality.

4. There is no entitlement to publication or permanent availability of individual content.

Section 6: Rights of Use to Content (License to CNC Base)

1. Users generally retain all rights to their content.

2. By uploading, the user grants the Provider a non-exclusive, worldwide, royalty-free, transferable and sublicensable right to store, reproduce, distribute, make publicly available and technically process the content (e.g. compression, creation of preview images/thumbnails, and machine translation pursuant to Section 2(5)) as part of platform operations, to the extent necessary for display — including on the Platform’s other domains —, hosting, security, moderation and further development of the Platform.

3. The user may end this grant of rights by deleting the content or the account, provided that no statutory retention obligations or legitimate interests (e.g. abuse prevention) prevent this.

Section 7: Downloads of Community Content

1. Content and files in the community area frequently originate from users. Which use (e.g. private/commercial, editing, redistribution) is permitted follows from the respective license/notice on the specific content or from statutory provisions.

2. If no explicit license is stated for a piece of content, files generally may not be reproduced, published or used commercially beyond statutory limits without permission from the rights holder.

3. To protect against abuse, limits apply to community downloads (currently: 3 downloads/24 h when not signed in, 30 downloads/24 h when signed in). These limits only concern community content and apply independently of the Plans and quotas under Section 11.

4. It is prohibited to circumvent technical measures restricting access or to systematically retrieve content in bulk.

Section 8: Prohibited Content and Actions (Short List)

In particular, the following are prohibited:

  • content involving legal violations (copyright, trademark law, personality rights, protection of minors, etc.),
  • malware, phishing, manipulation, security attacks,
  • impersonating other identities,
  • content that serves exclusively for advertising/lead generation (spam), unless expressly permitted.

Section 9: Reports, Notice-and-Takedown

1. Users may report content if it appears unlawful or infringes rights (info@cncbase.de).

2. Reports should, if possible, include: link/project, description of the issue, proof of entitlement (e.g. rights ownership) and contact details.

3. The Provider will review reported content and take action if necessary (blocking/deletion).

Section 10: Donation Links

CNC Base allows users to add a personal donation link (e.g. Buy Me a Coffee) to their profile. It is displayed publicly on the user’s profile and project pages. CNC Base is not a party to such donation transactions, does not charge a commission, and assumes no liability for external donation services.

Section 11: Paid Tools and Digital Content (Single Purchases and Plans)

1. Offering. You can purchase paid Tool Files

  • as a single purchase (“pay per download”): by default €1 per file/format; the 2D bundle (all 2D formats of a tool design) costs €2. Deviating prices for individual tools are displayed before purchase;
  • under a Plan (annual subscription): Free (€0), FJB Pro (€20/year, valid only on fingerjointbox.com), LHG Pro (€15/year, valid only on livinghingegenerator.com), CNC Base Pro (€30/year, valid on all sites of the Platform) and CNC Base Business (€300/year, valid on all sites of the Platform).

The current scope of services and prices follow from the pricing page of the respective website; they become part of the contract upon purchase.

2. Conclusion of contract. The presentation of the tools and Plans on the Platform is not a binding offer but an invitation to place an order. You place your order by completing the confirmation dialog and the payment process with our payment service provider Stripe. The contract is concluded upon payment confirmation or provision of the service. You receive a confirmation with an order number by email; for purchases made with an account, your orders and the associated details are available at any time in the account area (“My Downloads”).

3. Provision. Tool Files are generated after receipt of payment and are usually made available within a few minutes. They can be retrieved in the account area or via a download link sent by email.

4. Guest purchase. Single purchases are also possible without an account. In that case, the files are provided via a download link that is valid for 7 days and allows a maximum of 10 retrievals per file. If you register later with the same email address, guest purchases are automatically assigned to your account and can be retrieved there again — within the storage period under paragraph 7. You are responsible for the accuracy of the email address provided during a guest purchase.

5. Quotas. The Pro Plans include 100, the Business Plan 500 Tool Downloads per calendar month. A “Tool Download” is any generation of a file initiated by you under your Plan; generating a file again with identical parameters also counts. For CNC Base Pro and CNC Base Business, one shared quota applies across all sites of the Platform; for FJB Pro and LHG Pro, the quota applies only on the respective site. The quota resets on the first day of each calendar month; unused downloads are not carried over and are not refunded. Once the quota is exhausted, single purchases remain possible.

6. Formats. 2D formats (currently DXF and SVG) are available as single purchases and in all Plans. 3D formats (STEP and STL) are reserved for the CNC Base Business Plan and are only available for suitable tools (box tools); 3D formats cannot be bought as single purchases.

7. Storage period. Generated Tool Files are kept available for re-download for a limited time: for single purchases and in the Pro Plans, 1 year from generation; in the Business Plan, until the end of the subscription plus 30 days. After that, the file is deleted; your order history and the saved parameter set are retained permanently and can be re-opened in the tool at any time (“re-open”). Generating a file again consumes quota or takes place as a single purchase. Please also keep your own copies of downloaded files.

8. Free tools. Selected tools can be used without registration or payment; in that case, file generation is subject to a daily export limit (currently 10 exports per day). The Provider may change the scope of the free offering (Section 2(4)).

Section 12: Prices, Payment, Invoicing

1. All prices are final prices in euros. No VAT is shown pursuant to Sec. 19 of the German VAT Act (UStG, small-business scheme).

2. Payments are processed by the payment service provider Stripe. The available payment methods are shown during checkout. Single purchases are due immediately; Plan fees are due annually in advance. Your payment statement shows a descriptor of the respective website (e.g. CNCBASE).

3. Invoices are provided electronically (by email or as a download). The user consents to electronic invoicing.

4. If a charge fails when a Plan renews, the Provider informs the user and retries the payment. The Provider may suspend the Plan benefits until payment is received; if the payment attempts remain unsuccessful, the Plan ends. Claims that have already arisen remain unaffected.

5. If a payment is refunded or reversed (e.g. chargeback), the right to further retrieval of the affected Tool Files lapses; associated download links are deactivated.

Section 13: Term, Renewal, Cancellation

1. Plans have a term of 12 months from purchase and renew automatically for further periods of 12 months each unless cancelled before the end of the current term.

2. The Provider reminds the user by email in good time before renewal (currently about 7 days in advance).

3. Cancellation is possible at any time with effect from the end of the current term — while signed in, via the pricing page or the customer portal (Stripe), or by email to info@cncbase.de; a cancellation by email must be sent from the email address associated with the account or include other proof of your identity. The cancellation is confirmed by email; the Plan can be reactivated until the end of the term.

4. A Plan change (e.g. from FJB Pro or LHG Pro to CNC Base Pro or CNC Base Business) takes place via the customer portal; fees already paid are credited pro rata. Site Plans and platform-wide Plans are not run in parallel.

5. When a Plan ends, the account falls back to the Free scope. Files generated under the Business Plan remain retrievable for 30 days after the subscription ends (Section 11(7)); order history and parameter sets are retained. The license to Tool Files already generated is governed by Section 15.

6. If, during the term, the Provider discontinues a tool or file format that is material to the Plan, or changes it materially to the user’s detriment, the user may terminate the Plan for cause; fees already paid are refunded pro rata in that case.

7. The right of both parties to terminate for good cause remains unaffected.

Section 14: Right of Withdrawal for Consumers

1. Consumers have the statutory right of withdrawal for single purchases (contracts for the supply of digital content) and for Plans (contracts for digital services) in accordance with the following instruction. Entrepreneurs have no right of withdrawal.

Instruction on Withdrawal

Right of withdrawal

You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of the conclusion of the contract.

To exercise your right of withdrawal, you must inform us (3 Layer Prototyping, Valentin Lenz, Torfstraße 19, 13353 Berlin, Germany, email: info@cncbase.de) of your decision to withdraw from this contract by an unequivocal statement (e.g. a letter sent by post or an email). You may use the model withdrawal form below, but it is not obligatory.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you without undue delay and in any event not later than fourteen days from the day on which we are informed about your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

If you requested that a service begin during the withdrawal period, you shall pay us an amount which is in proportion to the services already provided, up to the time at which you inform us of the exercise of the right of withdrawal with regard to this contract, in comparison with the full scope of the services provided for in the contract.

— End of the instruction on withdrawal —

2. Expiry for single purchases: For contracts for the supply of digital content not delivered on a tangible medium, the right of withdrawal expires if the Provider has begun performing the contract after you have expressly consented to the Provider beginning performance before the end of the withdrawal period and you have confirmed your knowledge that you lose your right of withdrawal by giving your consent once performance has begun (Sec. 356(5) BGB). You give this consent and confirmation at the time of purchase via a separate, unticked checkbox; the Provider confirms the conclusion of the contract and your consent on a durable medium (by email).

3. Plans: If you want a Plan to start immediately — before the end of the withdrawal period — you likewise give this consent via the checkbox in the order step. If you then withdraw within the deadline, you owe compensation for the value of the portion of the service provided up to the withdrawal (see instruction).

Model Withdrawal Form

Section 15: License to Tool Files

1. The tools, the underlying software, and the geometry templates and designs remain the intellectual property of the Provider. For generated Tool Files, you receive a non-exclusive, non-transferable right of use in accordance with the following paragraphs.

2. Free, single purchases and Pro Plans (FJB Pro, LHG Pro, CNC Base Pro): Tool Files may be used for private purposes only. In particular, passing on, reselling, publishing or making the files publicly available is not permitted, nor is the sale of products manufactured with them.

3. CNC Base Business: Commercial use is permitted, in particular the commercial manufacture and sale of products made with the files. Even under the Business Plan, passing on, reselling, publishing or re-hosting the files themselves is not permitted, nor is their use to build an offering that competes with the Platform. The license to files generated during the Plan term continues after the Plan ends.

4. Tool Files may contain a license notice (e.g. “For private use only”). Removing the notice does not change the scope of the license.

5. Making the account available to third parties and sharing quotas to circumvent the license or Plan limits are prohibited (Section 3(3), Section 18(1)).

Section 16: Warranty for Digital Products, Updates

1. For consumers, the statutory warranty rights for digital products (Secs. 327 et seq. BGB) apply to Tool Files and Plans.

2. During the respective provision period (Section 11(7)), the Provider supplies the updates necessary to maintain conformity of the digital product and informs users about them.

3. Tool Files are generated exclusively from the parameters you enter (e.g. dimensions, material thickness, kerf compensation, units of measurement). Properties resulting from your inputs are not defects. The Provider does not warrant suitability for particular machines, materials, manufacturing processes or tolerances unless expressly agreed.

4. Please address complaints to info@cncbase.de.

Section 17: Liability; Own Responsibility in Manufacturing

1. The Provider is liable without limitation for intent and gross negligence, for damages arising from injury to life, body or health, and under the German Product Liability Act.

2. In cases of slight negligence, the Provider is only liable for the breach of material contractual obligations (obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance the user may regularly rely), limited to the foreseeable damage typical for the contract.

3. The Provider assumes no warranty for content posted by users. Liability for third-party information only arises upon knowledge of a concrete infringement; upon becoming aware, the content will be promptly removed or blocked.

4. CNC/workshop risks with community content: files, plans and instructions from other users may contain errors. Use is at your own risk. Users are themselves responsible for review, safe execution, material selection, machine parameters, workplace safety and compliance with standards.

5. Tool Files: Tool Files geometrically reflect the parameters you selected; they are not individually reviewed. Check generated files for plausibility and suitability before manufacturing (e.g. with a test cut). You are responsible for machine configuration, tooling, feeds, material selection, workholding, workplace safety and compliance with applicable standards. Paragraphs 1 and 2 remain unaffected.

6. Indemnification: Users shall indemnify the Provider against third-party claims (including reasonable costs of legal defence) asserted due to content posted by the user or unlawful use of the Platform, provided the user is responsible for this.

Section 18: Account Suspension and Deletion

1. The Provider may temporarily suspend user accounts, or permanently close them in serious cases, for violations of these Terms — in particular of the community rules (Sections 4, 8), the license provisions (Section 15), or through misuse of quotas or access credentials — as well as to avert danger.

2. Users can delete their account themselves at any time in the settings. Upon deletion, the user’s content (e.g. projects and comments) is deleted and the member record is anonymized; order and invoice data remains stored due to statutory retention obligations (see the privacy policy for details).

3. Active Plans end upon account deletion; fees already paid for the remaining term are not refunded.

Section 19: Data Protection

Personal data is processed in accordance with the privacy policy of the respective website. Account, order and download data is processed centrally for all sites of the Platform.

Section 20: Changes to These Terms

1. The Provider may amend these Terms with effect for the future where there is a valid reason to do so (e.g. changes in legislation or case law, new or changed features, technical or security-related requirements). Prices and the main performance obligations of active Plans are not changed by this route.

2. For free use: registered users will be informed of material changes in an appropriate manner. If the user continues to use the Platform after the changes take effect, the new Terms are deemed accepted, to the extent permitted by law.

3. For users with an active Plan, the Provider announces changes by email at least six weeks before they take effect. If the user does not object within the period stated in the announcement, the changes are deemed accepted; this consequence is pointed out separately in the announcement. In the event of an objection, the user may cancel the Plan effective as of the date the changes take effect; fees already paid for periods thereafter are refunded pro rata.

[ANWALT: Align the amendment clause with the German Federal Court of Justice case law on deemed-consent clauses (XI ZR 26/20, “Postbank”); finalize the notice period and the permissible scope of changes.]

Section 21: Final Provisions

1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers habitually resident abroad, the mandatory consumer protection provisions of their state of residence remain unaffected (Art. 6(2) Rome I Regulation).

2. If the user is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Berlin.

3. The Provider is neither willing nor obligated to participate in dispute resolution proceedings before a consumer arbitration board.

4. The contract language is German. The English version of these Terms is a non-binding convenience translation; in case of discrepancies, the German version prevails.

5. Should individual provisions be or become invalid, the validity of the remaining provisions remains unaffected.
