Magnet Ball Bearing Spinner Fidget, Update 1 inch
thingiverse
drfamulac just asked me to scale the bearings to 1 inch (25mm). I don’t have 1 inch bearings, so I can’t test it if it fits, but I scaled it. Note: If the balls do not slide with light pressure in their housing, take a hair dryer and heat the housing. But be careful, 1, 2, 3 seconds are sufficient. Just try it, have fun.
