Here is my first attempt on some planetary gears. I just used project board for a test and it works perfect! All the gears mesh up great. I attached is the CC file for anyone else to use. If you use it please post your results!
Its been a year since i posted this, so if i remember correctly i did an outside cut. make sure that when you are set the cut that its cutting the outside of the gear and not the inside. hope this helps!
