100:1 Compound Planetary Gear Reducer

####Featured In These YouTube Videos:
- Two in series https://youtu.be/wsk3gqiS__M


#####Torque Capabilities
Please know that i designed this gearbox for a demonstration model so that it would be easy for everyone to understand how a compound planetary works, for that reason i omitted the 3rd module that increases the torque capabilities.
Because of that, this gearbox cannot handle much load.

####How This Works
- 100 Turns of the input sun gear will result in ring gear #2 making one full rotation.
These are designed to be able to mount them in series on the channel, or drive them with the included stepper motor mount. You will need to scale the channel longer if you want to use two gearboxes and the stepper motor mount on the same channel, but keep in mind it is very boring to watch the second gearbox rotate, as it is very slow.
- This gearbox can not be back-driven, every piece of plastic on it will snap before you get the input to turn.
