This was a small side project that was created because of a design flaw in a different project. All pieces can be printed at the same time without any supports. Infill is up to your own preference, I used 10% with a .2mm layer height. No parts are fixed in place though you could glue the stems to the gears and rings.

1 Ring Gear

1 Sun Gear

1 Base

5 Stem Connectors

1 of each of the Rings

2 Planet Plain

2 Planet Stem

Could be remixed to have more satisfying rotation but was just a fun side design.
