Fidget Spinner with internal weights

This is based off of Duke T's fidget spinner where the weights are inside the spinner. According to Duke T's instructions, this fits 3 pennies or 1 3/4" x 3/16" button magnet. The pennies fit for me, but the magnets did not. I redid this from scratch in Fusion 360 with bigger spaces for the magnets.

The real photo is one that I did with Hatchbox Wood PLA. I sanded it with 600 & 800 grit sandpaper, stained it, and then polyurethaned it. This does have the magnets in it.
