Slightly-Less Itty Bitty Fidget (12x1mm magnet)

This is the excellent 3D Printy Itty Bitty Fidget, scaled at 150% to fit 12mm x 1mm magnets. Top takes a lot of effort to snap on, but it does fit. The magnets need to be glued in (I use tacky glue & let it sit half a day). To snap back & forth, the button magnet has to be the opposite pole to both the case magnets, but I found out by accident that if one of the case magnets is the same pole, there's a satisfying resistance & snapping-back of the button.
