Arduino Robot Wheel

Remixed from scratch using existing mesh as a reference to clean up geometry and errors.

Also tapered the shaft 1 degree for a nice snug press fit.

Also added a version with built in supports for less time and material usage, but I didn't like the way it printed because the walls are just too thick on the supports and there is too much empty room between them -- IE it still needs added supports. Use that version at your own risk.
