Atom and Curved Marble Spinner

thingiverse

I was crafting spinners for my young ones and suddenly found myself running out of bearings to utilize as weights. We have an abundance of marbles lying around, so I made some modifications to a couple of spinners to use 15.5mm marbles instead of steel weights or bearings. Standard marble size typically ranges from about 15.5 - 15.7mm. I designed the modified spinners in such a way that the marbles can be easily replaced if they want to mix and match different colors. On the curved spinner, I made a precise cut so the marble can be inserted smoothly and securely. To make this cut, you can use a razor blade or a small saw.
