Trial and error...
After printing dozens of test gears, the first fitting is close enough.
Almost fully assembled. Only the lunar orbit gear and planetary models are missing.
@th Wow!! Do you think it could be fully 3D-printed? Or is the rigid frame essential?
@blinry the three side supports will be 3D printed, although I'm having problems with the printed main shafts not adhering well enough under torque. There are some snapped ones in the pile of gears photo...
