Testing a 3D-PRINTED HARMONIC GEARBOX with a BUILT-IN MOTOR

In this video, I tested a viral harmonic reducer design from an FRC robotics team. You can find the CAD by searching "9312 OFF Season Project - NEO 550 Harmonic Gearbox". Though the performance wasn't ideal, it was still a rewarding experience learning about the internal structure and working principles of harmonic reducers. Feel free to point out my mistakes - I'm here to learn too!
