Summary This is the file of a simple gear clove, you can scale in little or big as you want. If you print it 6 times the same file, you'll be able to assemble a complete gear, even in a very big scale as shown in the picture. Easy to print, flat with a little support. All the best! PLEASE NOTE: I add a new release "ingratenon.stl" with tenons after the request of Tibuck: you have 3 joints for each side, calculated with tollerance 0.2 - the little tenon must be printed twice. No problems with the internal overhangs, even if the bottom surface will be bad you can always join everything with bi-component glue or epoxy.
