Nema 17 16:1 Gearbox
thingiverse
I designed this gearbox to fit onto a nema 17 stepper motor, whilst also being able to be mounted where a regular nema 17 can be mounted. [](https://www.youtube.com/watch?v=87yFGr4fGRY) The above video shows it running as well as assembly instructions! (Click on the image) Alternatively, written instructions are available here: https://www.instructables.com/id/3D-Printed-161-Nema-17-Gearbox/ This allows you to increase the torque in many applications without redesigning the machine you will be using this on. It has 3 pairs of 12 tooth gears turning 30 tooth gears, so that gives 3 reductions of 0.4. This results in the gearbox having a ratio of 15.625:1. Meaning that every 15.625 revolutions of the motor, the gearbox shaft will rotate once.
