NEMA 17 1:48 hypocycloid test

thingiverse

Here is my very first test of my new hypocycloid gearbox generator - working perfectly as printed! I've shared the scad file online at http://www.thingiverse.com/thing:481167 for anyone who wants to try it out. As soon as I get my camera back, I'll post some pics so you can see what I'm working with! This first test shows that the gearbox actually works, which is awesome! That being said, there are still a few areas where I think I can make improvements. Right now, the motion output seems a bit jerky - not smooth like I'd like it to be. Maybe changing some of the parameters in the scad file (like the peg diameter) would help with that? Even so, I'm really stoked that my test showed that the thing works as intended! I know my scad file could use a bit more polishing - sorry for not getting that all sorted out just yet! I've made sure to include a list of materials and hardware you'll need to build this gearbox: You will require: 2x 10 mm ID / 15 mm OD bearings, which are about 4 mm high in height. You will also need 2x 6 mm ID / 19 mm OD bearings, with a similar height of 6 mm. I have included all of the parts for building the gearbox that is made using this design. - 1 threaded M6 shaft, around 70mm in length. It needs four high-capacity, M3 cap screws. Also you will need: 4 to 6 10 or 15 mm M3 cap screws, as well as the matching nuts.
