JAGS (Just Another Gear Spinner)

thingiverse

This gear fidget spinner is somewhat unique in the fact that it uses bearings only for the outer gears. The inner gear has no bearing and is held in place by -- and only has contact with -- the outer gears. Obviously, it has too much friction to spin freely for any length of time. Several seconds max. If anyone can adapt and CNC this from aluminum (or some other metal) I'd love to see how well it works. The center gear will probably need supports, depending on how well you can make your printer bridge. Also note, the finger pads are included with the body .stl, but I also included a separate .stl for each in case someone wants to change the finger pad to stick out a little from the sides of the completed spinner.
