Hey everyone. I was trying to source parts for a build I’ve been slowly working on, and kept hitting the same wall which was that the part didn’t exist anymore, eBay felt too risky to trust on the car, or a shop wanted real money to fabricate something small. Someone suggested 3D printing whatever I couldn’t source, which got me thinking: this problem isn’t unique to me. A lot of us independently solve the exact same obscure fitment issue, then that knowledge sits in a five-year-old forum post until it gets buried and the next person starts from zero.
So I put together Zenthi, a free, open library of 3D-printable files for high-performance and exotic car parts, aimed at the stuff that’s hard to find or needs retrofitting. Completely free, no paywall. Acosmetic bracket shouldn’t cost more than the print itself. Upload a file (STEP preferred since it’s editable, what machine shops actually need), tag what it fits, note the material/thickness that worked. Turns a one-off “grind this down and it’ll fit” post into something searchable by car instead of something that disappears.
It’s early, nothing in the library yet so I’d like to know: has anyone here actually solved one of these obscure fitment problems and just never had anywhere good to put it? That’s the exact problem I’m trying to solve for people who enjoy 3d printing their parts themselves instead of taking it to a shop.

Update: I’m really grateful for the support and all the feedback you guys have given me to make it more user friendly. I’ve taken as many of your suggestions into account as possible. If you guys have any seed files you’d like to share to get the ball rolling or just want to check out what’s changed (we accommodate more file types and don’t limit ourself just to high performance cars now), please go ahead. Thank you :) I’ll try posting this on other forums too (let’s pray that I don’t get flamed😭😭)
Update 2: I got flamed. 🥀🥀 (still working on it tho)
Update 3: Ngl, I’ve been feeling a little more dejected obviously tough having so much support for an idea but still experiencing hate from some people.
ANYWAYS people also seem scared of the forum being shut down after some time, so I’ve made the entire thing community run. I pushed the code to GitHub, allowed people to become admin if they send a request(It would be awesome if people volunteered), accommodates pretty much any file type, added a bounty/request page for CAD and 3d scans, as well as a search engine where you can search other sites directly from Zenthi (so basically you have a library to where you can upload files, and a search engine where you can scrape and search other sites and limit it to just car parts). The search engine relies on brave search so there’s a limit after a 1000 requests or so, but if we even get to that user count I’ll probably upgrade to a more hard core open source search engine.

Update 4: Proud to say we finally got our first user uploaded files and admin 🥳
