Wheel for use in Caster FEATURES ABEC BEARING INTERGRATION!

This wheel was designed for use in a caster for a line following robot that I am building. It's central hole allows for an ABEC skating bearing to fit inside tightly making for a good smooth wheel.

As you can see the outside of the wheel isn't circular... That's Sketchup's circle tool not me! I've learned a method of working around it but I can't do it with this model.

By the way, this wheel can work without the caster brace that I'll upload later however, it doesn't have a lot of friction
