Robot Wheel

This is a cool robot wheel I designed during my lunch period. :) It is scalable, But if You scale it, remember to adjust the axle hole size. I usually make mine at 50% size.

This might actually make a decent flywheel if made of metal.
It was supposed to be a pulley, but made a better wheel.

UPDATE:
I added a wheel with five spokes instead of three. It is also smaller.
