Proper Polymer

Proper Polymer is a one-person operation built around a simple idea: make high-quality, functional STL files for Toyota Tacoma owners and off-road enthusiasts who want parts that actually fit.

Every design starts in CAD and gets validated against a real 2020 Tacoma TRD Off-Road. If it doesn't fit in the real world, it doesn't ship. That means accurate mounting points, real-world tolerances, and geometry that's actually optimized for FDM printing — not just something that looks good in a render.

Based in the Pacific Northwest, where the trails demand gear that holds up and the weather demands materials that last — PETG and ASA are the defaults here for a reason.

This isn't a big brand. It's one person who loves trucks, printing, and solving real problems with well-designed parts. If something's off with a file, I'll make it right.
