Check out the new version here: https://www.printables.com/model/1143579-motor-wheel-v2

I made this because i needed a wheel for an antweight robot so i desinged this. For tires use silicone. The total wheel size is 40mm.  Fits N20 motors there is a 3mm hole for a screw and a 4mm hole for the mold. the screw should be longer then 10mm.
