A functional and fun set of planetary gears that look like they should not work...but they do. Based on Reuleaux Triangle bearings and shapes of constant width. Have fun!
Note: While I have printed these files successfully on my CR-10S with minimal issues, it seems like a lot of users are having problems with clearance. In response, I have uploaded the individual components, that can then be assembled post-print by flexing the external ring gear.

Initial height is fairly critical so that close tolerances inherent in model do not result in fused parts. Other than that, should pop off the build plate in functional form.
I keep speed at 25mm/s for first layer then 45mm/s.
