gear fidget, print-in-place

Since I recently started playing with gear designs, I made this and found it nice enough to share, even though quite similar things exist already. I had quite some fun fidgeting with it.

Printing: 

0.4mm nozzle, 0.2mm layer height, random seams, 3 perimeters, concentric bottom and top infill.

Assembly is not required, but a well dialed in printer (with good tolerances) is.

Movement might be rough at first, but after some breaking in they should turn smoothly.
