Gears Are Awesome!
This is a sweet little design I did back in August and I just got to uploading it. This can be printed as one print on almost any 3D printer and then assembled by just fitting the pieces together. All of the gears turn and work great, even though it made need to be broken in a little before it will start turning really smoothly. I have printed this myself and it works great. I will upload pictures of it as soon as I get back to my dorm (right now I am home for Christmas). I hope you enjoy it.
P.S. I am working on a derivative of this that will actually turn a propeller. So check back later for this design.
