Kid's Car Wheel polygon

thingiverse

This is the exchange part for the wheel mount onto the gear box of kid's cars. It is necessary for 35W motors (and gear box) to be used with wheels for 25W motors, as the polygon is approx. 2mm wider. It is designed to use the original screws to fix onto the wheel. Hint: As it is wider than the original, the cars axle needs to be replaced with a longer one (10mm diameter steel rod).
