Teensy 3.0 meets 3D printer I learned how to model involute gear forms so I printed up this 6:1 (12 tooth pinion:72 tooth idler) 20deg contact angle gear set.
It's printed in ABS at .24mm slice thickness. The large gear is 150mm in diameter. It's operated by a stepper motor, controlled by a Teensy 3.0 and a Panucatt SureStepr SD8822 stepper motor driver. In this video, it's running at 32 microsteps /step, with low acceleration. I'm amazed at the torque this thing can produce
