Open library · Rev. 01
Rare parts. Real fixes. Built from scratch.
Where car part innovation happens — rare fixes, retrofits, and hard-to-find parts for any car. The hardest, most inventive fixes usually come from high-performance and exotic builds pushing into territory nobody else supports — measuring the broken bracket, modelling it at 2am, printing five revisions until it clicks in. Zenthi is just as much for the small stuff: a discontinued washer fluid splitter or a clip you can't find anywhere is just as welcome as a Lamborghini retrofit. This is where those fixes live instead of disappearing into old forum threads.

How it works
Someone solves it
A cracked HVAC vent clip on an old 911. A dead sensor housing on a Diablo. A snapped washer fluid splitter on a Bronco. A better bracket for a Civic. Somebody already modelled a replacement.
It gets shared here
Upload a CAD model, 3D scan, cutting profile, or 2D drawing — STEP is recommended for edits, but the library accepts multiple formats. Add fitment details and a writeup so the next person knows exactly what they're looking at.
It stays findable
Reviewed, catalogued by make, model and year range, and free to download forever — not buried on page 14 of a thread. Files aren't just for printing either: they're a reference you can measure, study and reverse-engineer a part from.
What Zenthi does
A searchable parts library
Free downloads, catalogued by make, model, year range, engine and category. STEP, STL, OBJ, PLY, DXF, SVG, PDF and DWG, with in-browser previews.
Browse the libraryUpload with proper credit
Original, re-shared or modified files all welcome. Fitment details, part numbers, material and print notes, plus source and licence tracking. Everything is reviewed before it goes public.
Upload a fileA request board
Can't find a part? Post it and someone with a scanner or CAD skills can claim it. When their file is approved, the request is marked fulfilled automatically.
See open requestsSearch the web
Search other model sites by the same fitment filters — no keyword collisions. You get the title, thumbnail, licence and a link to the original listing; Zenthi never rehosts the file.

If you can't find it, it probably belongs here.
Pretty much anything car-related that someone else might need someday: brackets, covers, clips, housings, adapters, trim, and weird one-offs. Mods, retrofits, upgrades, and everyday fixes are all welcome — from a Bronco's broken washer splitter to a Lamborghini retrofit nobody else makes. The only hard rule is safety: printed polymer has no business holding a car together or containing fuel. Use files for fitment and reference only, and verify fit, material, and safety yourself before any real-world use.
A note on brand coverage: Honda/Acura and Stellantis-brand vehicles (Chrysler, Dodge, Jeep, Ram, Fiat, Alfa Romeo, Maserati, Peugeot, Citroën, Opel, Vauxhall, Lancia) currently aren't supported. These manufacturers have a documented history of aggressive legal takedown action against community fitment files, even ones with no logo or trademark use — we'd rather not put contributors at risk.
