I needed a very high nema 17 stepper reduction in a small space, and nothing quite met my requirements. This takes care of that, while keeping the same form factor as a stepper motor. You can easily put this in line with your stepper, and just mount both. You only need to adapt the output to your application. Instead of using expensive and heavy specialty bearings, I just put 4mm ball bearings between the eccentric shafts and cycloid disks. It takes anywhere from 6-12 M3 screws (depending on your torque-weight requirements), and 18 4mm ball bearings.
