3D Printed NEMA 17 Precision Gearbox with Position Feedback!

I’m so thrilled to present the final design of my 3d Printed Gearbox for a NEMA 17 stepper motor. The new design is a major improvement on the first prototype in so many aspects, just to name a few things: stronger construction, a lot of mounting points, position feedback with a hall effects sensor, more gear reduction and thus more torque. The video has been some time on the way now, and has taken quite some effort, so I really hope you enjoy it!
