Magnetic knuckle roller set

A simple, compact fidget toy. Each roller measures 55mm long and tapers from 15mm at the ends to 6mm in the middle. It is available in two styles, smooth or knurled, depending on your grip preference. Each roller contains four 10×2mm magnets, so a full set requires eight magnets. The magnets should be glued in place with the end caps to keep them secure and prevent rattling. Check out my other fidget designshttps://makerworld.com/en/collections/7776545-fidgets
