Spinny McSpinface - Tumbler Turner

There are other versions of this concept that others have made.  This one is fully enclosed and has is named Spinny McSpinface.  Because what else would you call it?

I have attached a kind of lathe chuck to mine so it can grip more shapes than just tumblers, but… a better more light weight solution is needed.

This was built around a 37mm, 12v eccentric output shaft motor and a RioRand low voltage controller.  A series of threaded inserts are used to screw down the support as/where needed.
