"Mag" wheel for FRC robot

This is one of a series of wheel prototypes FRC team 2363 delevoped. This wheel is for a 1/2" hex shaft. It uses 1 1/2" wide tread. When the tread is attached, the OD would be ~4".

In ReplicatorG software, the wheel goes face down on the bed, and is grown using "full support". This keeps the upper lip of the rim properly supported.
