TT Motor Wheel

I appreciate that TT motor wheels are cheap, but we are working on an extremely cost-sensitive little robot car kit. ScotBot is coming, but for now… the wheel. The wheel is parametric, and so can be edited to suit. The default size is perfect to take a No 81 (2" x ½") rubber band as a “tyre” for add traction.

The wheel is a good friction fit onto generic yellow TT gearmotors, but for that extra level of rightness and security, there is a hole suitable for an M2x3mm self-tapping screw to go through the wheel and into the hole in the motor shaft.
