Robo 3D Maker Coin (unofficial)

A coworker had shown interest in 3D printing, so whats a better way to share the fun than with a spinning maker coin! Given my first venture into printing was with my Robo 3D R1 +, I thought it was fitting to make a coin in their honor.

* Update 5/18/18 - Gap widened slightly for ease of rotation. Divot added for finger/thumb grip.
