#### What it is?
- This is what I call a CDCP, or a Carrier Driven Compound Planetary. It is very similar to a typical compound planetary, except for the fact that it does not have a sun gear, thus the input becomes the carrier. when you spin the carrier 20X the second ring gear will make one rotation. (depending on which way you are holding it)

#### Print Settings!
- This assembly requires a LOT of precision in your printer. Before printing it, make sure to change your nozzle, tighten your belts, calibrate your printer and print it extremely slowly.
- You might also consider using a negative horizontal expansion setting in your slicer.
- The fusion 360 file includes a parameter for bearing clearance, it is default set to leave .2mm clearance over or under the bearing diameter, you can adjust this in the parameters window.

#### Hardware Required!!
- 2X 6808 bearings for the ring gears https://www.amazon.com/
