Ball Bearing Spinning Toy
thingiverse
I used two 13mm diameter steel bearing ball and a 15mm diameter by 2mm thickness magnet. You only need one steel ball and magnet for it to work. IMPORTANT!! The ball bearing needs be placed while the print is getting made. It will not fit after print is complete because top hole is too small and the bottom is sealed. I also have a spinning rocket model you can download
