Cardboard Battlebot Gearbox

High-torque 3D printed gearboxes designed for a weight-constrained Cardboard Battlebots competition.

Following a "Cardboard Battlebots" competition I was somewhat underwhelmed with the level of destruction. We were constrained to using the same motor so, for the greater good (or bad?) I designed and open sourced gearboxes for the class to maximize destruction in the tournament's next iteration.
