Gas Cap Holder V3

For V3, I redesigned the holder with a rounder shape, stronger magnets, and a carbon fiber texture. I went through test prints in November, fixing the errors one print at a time until the fit was right.

Preorders opened December 1 and shipped December 24, and the regular sale on January 2 sold out too. Miata Performance House, a page with 27k followers, featured it in a video that got 23k views.
