I screwed up when exporting so all parts need to be scaled up by 2540.00%.

This is made for dual extrusion. To center the numbers on the gear make the number's x-y-z coordinates the same as the gear they go on. I used simplify 3d so I don't know what other software needs for dual extrusion, but I can upload other versions of this for different programs if need be.
