Custom projects

SKETCH → DESIGN → PRINT
1

Sketch your idea

Text or email us a rough drawing or a photo — no CAD needed. Tell us the color and how the part will be used so we can match the right material to the job.

2

We design it

We model your part in Autodesk Fusion and send you 3D renderings so you can see exactly what you're getting before anything hits the printer.

3

We print & ship

You approve a printed proof, we run the final part and ship it within 48 hours. Fit it, race it, and tell us what to build next.

The right plastic for the job

Race parts live a hard life — heat, vibration, fuel, and the occasional wall. We match every part to a material that can take it, and we'll tell you exactly what your part is printed in.

PETG Tough, fuel-resistant, the workhorse
ASA UV-stable for parts that live outside
ABS Handles engine-bay heat
TPU Flexible for grommets and bumpers
