Vehicle-specific 3D parts,
fitment-confirmed by the community.
Trimspec is a vehicle-aware catalog of 3D-printable accessories for the cabin, console, and trim — built so owners of discontinued trucks, older imports, and unusual trims can find parts by search, not by digging through generic model repositories.
- Year → trim
- fitment-scoped
- STLs confirmed
- by community fitment logs
- Parts in scope
- accessories & utility
The catalog
Parts that fit the vehicle, the printer, and the install.
Five families of accessory-grade hardware. None of it safety systems — the focus is the cabin, console, and trim where 3D printing delivers the most value.
What’s hot on the workshop floor.
Two live feeds straight off the catalog: the parts everyone’s grabbed, and the parts somebody pulled down in the last few hours. Both update every time someone hits Download.
How it works
A catalog that gets more truthful the longer it runs.
Trimspec prioritises the long-tail: vehicles where there’s no aftermarket. Every part has a fitment log, every log is open to the community, and confirmation drives what rises to the top.

Drill year → make → model → trim
Every part page starts with a fitment picker that scopes to your exact vehicle — not a generic model repository.
Confirmed by the people who printed
Each STL has a running log of install confirmations, photos, and notes — so you know it fits before you spend 14 hours of filament.
Recommended print settings included
Layer height, infill, orientation, and the print-time estimate are attached to the STL — no forum archaeology required.
My Garage
Save your vehicles. The catalog does the rest.
Type your year, make, model, and trim once. Parts that don’t fit your vehicle are hidden, and the listings that DO fit are prioritised — so you stop scrolling through garbage that won't mount on your truck.
- Saved vehicles drive the parts list — every page scoped to what fits your exact build.
- Fitment log attached to every STL: photos, install notes, and ‘works on a 1996 XJ’ confirmation from real owners.
- Anonymity by default — confirmations are public, identity is up to you.
Wanted Parts board
New product, designed by what people actually need.
Post what you wish existed. Other owners vote. When a wanted post has enough demand, designers pick it up and the STL lands on the catalog. The board keeps momentum visible across four lanes.
Design bounties, premium membership, and a designer marketplace are intentionally out of scope today — but the catalog is built so they plug in cleanly when the community is ready.
Safety-critical, kept out
Not safety systems. Accessories, console, trim — and the long tail of small broken plastic that vendors stopped making.
Trimspec is intentionally narrower than the rest of the 3D-printing world. The platform is built around fitment confirmation, not part grade — and the audit will out- perform any safety claim on a printed brake caliper.
Out of scope by design
Brakes, steering, suspension, airbags, seatbelts and structural parts stay out of the catalog — the focus is accessories, organisation, replacement plastics, and utility hardware where 3D printing delivers the most value.
