Fidget Spinner Ring

My girlfriend jokingly told me that she would get me a wedding band with a little fidget spinner on it, and I figured that I have some spare ball bearings lying around, so I went and designed one. Rings of size O ½ and K ½ are included, feel free to scale as required. (note that you will need different bearings if you scale the model)Sizes correspond to diameters of 17.9mm and 16.3mm respectively. Use high speed low friction bearings (preferably bambu ball bearings)
