Gear Cube

grabcad

A set of conical gear parts that interlock to a central hub part to form a cube you can twist. My sister brought me home one of these 3d printed from some dork at MIT, and here is my shot at modeling it. This model uses A LOT of in-context references, so have fun deciphering that if you want to edit it or refine the gears. I WOULD NOT 3D print this hoping that it will all work. I fudged in the gear geometry as best as I could guess, and I'm a bit disappointed I couldn't find a creative way to make them work really well. If anybody can solve that riddle eloquently, I'm all ears, as I really don't know what I'm doing with gear teeth.
