This is a multistep Reducer incorporating a worm gear reducer and helical gear reducer. The model has a primary and secondary output. the secondary output can be used to get position feedback from the gearbox. There are 2 input options one with 50:1 reduction and another with 100:1. with some modification It can also be used to increase speed with 1:2 ratio and has the potential to give 50:1 reduction and 1:2 increase simultaneously. Other than the bearings all the parts can be 3D printed (NO static or dynamic simulation was done yet on the parts so do proceed with caution while using it).
