For trade partners
Your overflow CAD department
RPM Custom Design works behind machine shops, restoration builders, and fabricators who need production ready models faster than they can draw them.
Machine shops
You have the machines and the backlog, not the CAD hours. Send the part or the print and get clean, machinable models back.
Restoration builders
Discontinued trim, brackets, and one off pieces recreated from the originals so the build keeps moving.
Fabricators and performance shops
Mounts, adapters, and custom hardware modeled around real clearances before anything gets cut.
Product sellers and small brands
Turn a proven prototype into repeatable, documented files you can quote with any manufacturer.
Ship us the part or send photos and prints. We scan, model, and return files ready for your machines. No minimum volume, and no CAD file required to start a job.
