I made this design inspired by a Tiktok I saw a few years ago. It's a little quarter-sized coin with magnets glued in that allow you to fidget one-handed silently. Great for long meetings or out and about when you don't want to call attention to yourself.

For assembly, you'll need 4 M2x4 Flat head screws and 2 accompanying nuts. You will need a few 5mm diagonal by 2mm tall neodymium magnets, 5 of which are glued into the base, and an additional magnet for each button. I recommend only printing a max of 3 buttons, 2 was the sweet spot for me.
