Custom automotive part design

Parts that do not exist yet, designed around your vehicle and your build, modeled in parametric CAD and prepared for the process that will actually make them.

01

Designed around real fitment

Every part starts with the space it has to live in. Mounting points, clearance, hardware, and heat are worked out from measurements, scans, or reference photos before geometry is committed, so the first prototype fits instead of teaching you what to fix.

02

Built for a manufacturing process

A model destined for CNC aluminum is not the same model as one destined for a printer or a laser-cut blank. The process is chosen with you early, then wall thickness, radii, draft, and tolerances are set to suit it, which is what keeps quotes from shops reasonable.

03

Parametric and editable

Models are built with a clean, editable feature tree. When the build changes, the bolt pattern moves, or you want a second chassis variant, the part is revised rather than rebuilt from scratch.

04

Documented so any shop can quote it

You receive a dimensioned drawing alongside the 3D data, with the critical interfaces called out and everything else left open. That is the difference between a shop quoting confidently and a shop padding the price for unknowns.
