Epicyclic gear toy

thingiverse

After spending a year playing with a test epicyclic gear assembly, I decided to make it into a fidget toy. As these are fairly small parts, I didn't need help with bed adhesion. But if you have to, use a raft instead of a brim, as the leftover lip from the brim will make it difficult to clip together and the gears won't mesh as well. Assembly: Print 4 planets, and 1 of everything else. Slot the two top pieces together and the two bottom pieces. Clip the bottom pieces into the central hole of the sun gear. Clip the planet gears on the four clips of the top pieces. Fit the ring gear around the planets. Clip the top assembly into the outer holes of the sun gear. It'll be a little stiff to start with but once it wears in a little it'll be a delightful little toy to fidget with when you're procrastinating. https://youtu.be/I5OrArtY4Jw
