Process

How a project runs

Six steps from the first photo to a finished part, with a written quote up front and a review before anything is manufactured.

  1. 01Step

    Send it in

    Share photos, the vehicle year/make/model, and what the part needs to do. Ship or drop off the physical part if you have one.

  2. 02Step

    Scan or measure

    The part is 3D scanned or hand-measured. Broken and incomplete parts are reconstructed from the surfaces that survived.

  3. 03Step

    Model in CAD

    A clean, editable 3D model is built with real fitment, wall thickness, and hardware callouts, not a scan mesh.

  4. 04Step

    Review & revise

    You see renders and dimensions before anything is made. Revisions happen here, where they are cheap.

  5. 05Step

    Prototype

    Optional fit-check prototype in printed polymer so the part is confirmed on the vehicle first.

  6. 06Step

    Manufacture or hand off

    Production runs through qualified CNC, printing, or fabrication partners, or you take the files and run them yourself.
