I liked the other gear fidgets I saw, and wanted to try making my own for commercial use!

Prints great on my X1C with the provided profile, but you may need to adjust for expansion on less calibrated printers.

Random Z-Seam helps keep the gears from binding.
It spins better with high infill in the outermost ring (the rest of the gears don't need much infill) and it is already set up in the 3mf.

If you have issues with the spinning not being smooth when it slows down, just keep spinning it and it should break it in and smooth it out.
