This fidget spinner has no need for any fasteners, but uses 3D printed pins that click into place.
With a few drops of superglue on the tips of the pins everything can also be permanently assembled into place.

Use a little grease to lubricate the shafts which will make the gears spin quite freely after a few turns.

The increased size of the ring should also fit slightly bigger fingers.

The number of teeth on both gears are prime numbers.
So it takes a bit of brain action to figure out how many turns are needed to re-align both white indicators.

Note: as usual, the stereo images are of the cross-eyed type.
