Fidget spinner - Double planetary gear

Watch out for this unusual planetary gear with 2 rows of planets! Which is quite challenging to design properly! :)You can print this in place, without supports. I have created 2 sizes.SMALL is 84 mm in diameter.BIG is 134 mm in diameter and you can fit pencil in to the hexagons for better play! If you want smoother running grease the gears. :) This gearing is delicate with respect to dimensions and tolerances, if you change the scale of the models, it won't work properly.Boost MeI'll appriciate if you leave me a boost. :) After printing it is needed to “crack” the planet gears up and down a little when you hear “crack” they are free for moving. Do it on all 6 outer gears.
