Community guidelines

• Any car-related part file — 3D print models, scans, cutting profiles, and 2D drawings. STEP is preferred where you have it.
• Zenthi is not for trinkets or purely aesthetic/decorative items — we're looking for real functionality. The goal is to cut through the noise of the broader 3D-printing community (which is dominated by novelty items) and build something genuinely useful. Examples of what wouldn't be accepted: a rose-shaped cup holder insert, keychains, phone holders, decorative shift knobs, novelty coasters, or anything whose primary purpose is looks rather than solving a real fitment, repair, or fabrication problem.
• Safety-critical items (brakes, suspension, structural, fuel-carrying) are welcome as reference and fitment data only. Printed polymer has no business holding a car together or containing fuel.
• Parts for Honda, Acura and Stellantis brands (Chrysler, Dodge, Jeep, Ram, Fiat, Alfa Romeo, Maserati, Peugeot, Citroën, DS, Opel, Vauxhall, Lancia, Abarth) cannot be listed here, for legal-risk reasons.
• Reuploads need a source link, the original creator's name, and the correct license. Modified files need the original's license, and ND-licensed originals (CC BY-ND, CC BY-NC-ND) cannot be reshared as modifications.
• Multiple STEP, STL, and additional files per submission are fine and encouraged.

• The category matches what the part actually is.
• Fitment data is present and plausible — make, model, year range, engine details.
• Licensing is valid: source link, creator credit, and the ND / modification rules.
• No restricted-brand fitment.
• No obvious copyright problems — scraped commercial files, paid models, or ripped OEM CAD.
• Safety-critical parts are flagged reference-only.

• Don't approve your own submissions — leave them for another admin.
• Act in good faith; approve on the merits, not on who uploaded it.
• Repeated bad-faith approvals, or approving around these rules, can result in the admin role being removed at the discretion of other admins or the site owner.

Create an account, then submit a short request explaining why you'd be a good reviewer — your background with car parts, CAD, scanning, or moderating communities. An existing admin reviews the request and either grants the admin role or declines it. You'll see the status on your account page.

You don't need an account to browse the library or use the search engine — accounts are only needed for uploading, posting or fulfilling requests, and admin actions.
