- Print all parts without cogs with 0.25 mm layer height or thinner.
- Print all other parts with 0.20 mm layer height or thinner.
- Sandpaper all parts slightly and make sure they were printed as intended. This might not be needed at all for the parts printed in PET-G.
- Assemble the motor, MotorECU and Back.
- Glue SunGearA on the motor shaft using Loctite 648 and the mount tool.
- Assemble the rest according to the explosion drawing.
- Make sure it is functional by rotating the wheel by hand. If it does not work, more sandpaping or better printing may be neccessary.
- Run the motor for a bit to make the gearbox smoother. This could also be done by hand.
- Take it apart and lubricate the internal parts slightly with lithium grease.
- Assemble it again and use Loctite thread lock for the M3x4mm screws for preventing them from loosening.
