Classic and vintage cars reach a point where the OEM parts supply runs out — and on a 40- or 50-year-old vehicle, the part that fails is rarely the engine. It's a vent bezel, a console clip, a window-crank escutcheon, a wiper-linkage bushing: a small plastic piece nobody reproduces anymore. 3D printing fills that gap, so you're not stuck scouring swap meets, Hemmings classifieds, and eBay for a part that broke decades ago. We've quietly become a Rochester-area go-to for "I can't find this anywhere" automotive parts.
What we print
- Interior trim and clips — dash pieces, vent bezels, door-panel retainers, switch surrounds, ashtray and console hardware, seatbelt guides — the brittle plastic bits that crack and crumble with age and aren't reproduced.
- Under-hood and chassis brackets and mounts in heat-resistant materials for components that moved, were replaced, or were never robust to begin with.
- Custom-fit enclosures and adapters for modern electronics — hidden stereos, Bluetooth modules, sensors, dash cams, gauge pods — integrated cleanly into an original dash.
- Knobs, handles, and levers recreated to match the original texture and shape, or upgraded if you'd rather.
- Reverse-engineered replacements — bring us the broken part (even in pieces), the part it mounts to, or detailed photos and measurements, and we'll model and print a drop-in. (More in our blog post on reverse engineering discontinued parts and our design services.)
Material recommendations
Automotive interiors and engine bays are harsh environments — heat, UV, vibration, and decades of use. Matching the material to where the part lives is the whole game:
- ASA — UV-stable and heat-tolerant; the best choice for anything that sees sun (dash tops, exterior trim) or under-hood heat. Won't yellow or get brittle in a sunny windshield like cheaper plastics.
- ABS — closest match to the properties and feel of most original interior trim plastics; paintable, sandable, and easy to texture or finish to match the rest of the dash.
- PETG — tough, dimensionally stable, and easier to print reliably than ABS; a strong default for interior parts that don't see extreme heat.
- Nylon (PA) — for mechanical parts that flex or take repeated load: bushings, linkage parts, latches, snap-fit retainers. Wears well and resists fatigue.
- TPU — for weatherstrip retainers, grommets, bumpers, and anything that needs to be flexible or sealing.
For an under-hood part that needs to survive sustained high heat, tell us the temperature it'll see — beyond a certain point a printed plastic isn't the right answer and we'll say so rather than sell you a part that'll deform.
Typical use cases
- Restoration projects — sourcing the last few unobtainable interior pieces to finish a build correctly.
- Daily-driver classics — keeping a 1970s or '80s car on the road when a $4 plastic clip is the only thing standing between you and a rattle or a non-functional vent.
- Resto-mods and custom builds — adapters and enclosures to integrate modern electronics into a vintage dash without hacking up original parts.
- Small-batch reproduction — once we've modeled an unobtainable part, we can print a handful for a club or a marque registry, not just one (see small-batch production).
- Motorcycles, tractors, boats, and other vintage equipment — the same problem and the same fix; it's not just cars.
FAQ
I only have the broken part — can you still recreate it? Usually, yes. Even a part in three pieces gives us most of the geometry; missing chunks get rebuilt from symmetry and from the surfaces it mates to. The more context you can give us — the part it bolts to, photos of it installed, an exploded diagram from a service manual — the closer the first print lands.
Can you match the original color and texture? Color, often — we stock a wide filament range and can paint for an exact match. Texture, sometimes directly and otherwise via light post-processing. For a part hidden behind a panel it rarely matters; for a visible dash piece, tell us and we'll discuss options.
How much does a reverse-engineered part cost? It's the design (CAD) time plus the print. For a simple clip or bezel the modeling is a couple of hours; a complex assembly takes longer. We quote both up front so there's no surprise. Most jobs ship in about a week from approval.
Will a printed part hold up like the original? For most interior trim and many under-hood parts, yes — often better, since you're getting a fresh part in a modern engineering plastic rather than 40-year-old brittle ABS. For high-stress structural or high-heat parts, we'll tell you honestly whether printing is the right call.
How it works
For reverse engineering, send us photos (with a ruler in frame), measurements, or the broken part itself — drop it off in Spencerport or mail it in — and we'll quote both the CAD work and the print. For parts you've already modeled or sourced online, just upload the file. Most jobs ship in about a week from approval.
