Yes I know there are lots of fidget spinners out there; this was a test of how to embed parts - bearings and nuts (M10?) - into a 3D printed object. Laying down filament on top of the embedded parts didn't work especially well, so the holes are constructed so that the filament holding the metal parts in place can all be bridges.
