App Info Launch App

Very nice tolerances! Gears fit on posts and spin easily, posts fit in holes and press fit well. When assembled my gears are binding just slightly on two opposite corners, but I expect that if I were to spin them a few hundred times manually all of the binding would go away...it might be that one of my axis is just slightly off from a dimensional standpoint...

Did you need to make the holes a little bigger after printing?

The gears fit the posts just fine, and if the two posts were 0.25mm farther apart they gears would have turned without any binding. I used some plastic lube to make them turn very nicely.
