Pololu's wheels for a 3 mm D-shaft, from their own CAD — seven sizes from 32 mm to 90 mm, each a plastic hub moulded into a rubber tyre. Every one presses straight onto the D-shaft of a Pololu micro metal gearmotor; the four largest also carry two 3.1 mm holes 12.7 mm apart for a universal mounting hub. Pololu sell most of them in up to five colours and draw one geometry for all of them, so the size picks the wheel and the Material panel paints the hub. The 42×19 mm is the exception: one colour, and a clearance bore rather than a press fit.
