About this 3D model

This is a fidget toy and educational model I designed which uses four beveled gears meshed together. It can be used to explain gear ratios (turns at 2:1 to the body), beveled gears, gear meshing, etc. You can print all in one colour, but it looks best with gears being a different colour to the body and screws. It would also look great with four gears all of different colours.
