Electric Drive Add-on for Gatling Rubber Band Gun

This uses a stepper motor to add an electric drive for the Gatling Rubber Band Gun (http://www.thingiverse.com/thing:647475). The crank arm from the original Gatling Rubber Band Gun should be removed, and this add-on secured to the Rear Body using zip ties.

Requires a bit of electronics and soldering. Details are in the instructions.
