Getting car parts remade
Interior clips, trim pieces, knobs, covers and small brackets that dealers no longer stock, or only sell inside a costly assembly. Safety parts stay with certified suppliers.

Cars are kept for a long time. In the US the average light vehicle was 12.8 years old in 2025, and passenger cars averaged 14.5 years (S&P Global Mobility, May 2025). As a car ages, small plastic parts break first: the clip that holds a door card, the cover over a seat-belt anchor, the knob on a heater control, the catch on a glovebox or centre console.
Dealers often stop stocking these parts, or sell them only as part of a whole panel or switch assembly. A maker can remake many of them from the broken original or from photos and measurements, as long as the part is not safety-critical.
Parts makers commonly remake
- Interior trim clips, door-card and headliner clips
- Glovebox, centre-console and armrest catches and hinges
- Heater, fan and radio knobs; switch caps
- Covers and caps: seat rails, seat-belt anchor covers, screw covers, fuse-box lids
- Cup holders, coin trays, sunglasses-holder parts
- Interior brackets for non-safety items (trim, storage, accessories)
- Battery covers for remote keys (the housing, not the electronics)
- Exterior trim end caps and mirror-cap clips (non-structural)
Materials and processes
ASA
The usual choice for anything in a car: Prusa Research gives it UV and temperature resistance up to 93 °C, and it suits exterior parts.
PETG
Fine for parts that stay in the shade and away from the dashboard and rear shelf; Prusa says suitable below 80 °C.
Nylon or polycarbonate
For hinges, catches and clips that flex or wear.
Avoid PLA
It softens above 60 °C, which a car parked in the sun can exceed. Ask for PLA only for a fit-check prototype.
Don't have these remade
- Brakes, steering, suspension, wheels and hubs
- Seat belts, seat mounts and airbag parts, including airbag covers
- Fuel-system parts and anything in contact with fuel
- Engine-bay parts near the exhaust or turbo
- Lighting lenses and anything that must meet road-legal approval
- Child-seat parts and ISOFIX fittings
Buy certified originals for these and have them fitted by a qualified person. The safety page explains why.
Try these first
- Ask a dealer for the part number with your vehicle identification number (VIN).
- Search the part number with breakers' yards, dismantlers and used-parts listings.
- Ask your owners' club or model forum: someone may already have a file or a source.
If nobody sells the part at a sensible price, a maker is the next step.
Good to know
In the US, Massachusetts voters approved a motor-vehicle right-to-repair law in 2012 that led to a 2014 national agreement giving independent shops access to dealer tools and repair information. A 2020 ballot question on telematics data passed with about 75% of the vote but was challenged in court by automakers, so check its status (Repairer Driven News, November 2020).
Car interiors are hot places for plastics. Material choice matters more here than almost anywhere else: say where in the car the part sits.
What to put in your post
- Make, model, year and VIN or the part number from the dealer's catalogue.
- Where the part sits (dashboard, door, boot) and whether it gets direct sun.
- Photos of the part and of the mounting points it clips into.
- Photos from every side with a ruler in shot, and the measurements that matter. The measuring guide shows how.
Step by step: find the model number, measure the part and photograph it for a quote.
