Inspired by more than remixed as I had to redesign for size, but wanted to make a strain wave gear for a 28byj-48 motor. Yes it is very slow, but the torque output is very good for a 5V unipolar motor. I am going to mod the 28byj48 motors to be bipolor motors to see the outcome of that in the near future. Here are the print details. All of the parts were printed out of the same PLA Plus material, however, I have a feeling that the flexspline would perform better if printed in PETG.
- Material: Duramic Black PLA Plus
- Print Temp: 215C
- Bed Temp: 60C
- Printed Parts Infill:
- flexspline: 100% infill
- cam_top: 100% infill
- cam_pin: 100% infill (print 2 of these)
- cam_bottom: 100% infill
- input_case: 20% infill
- output_case: 20% infill
- test_arm: 20% infill
- wave_gen_top: 100% infill
- wave_gen_bottom: 100% infill
- Hardware:
- 2-M3X4 Hex Screws for mounting the motor

- 4-M3 Hex Nuts for closing the case
- 4-M3X16 Hex Screws for mounting the test arm
- 2-623zz bearings for wave generator
- 1-6805 bearing for output
