A newer and better version of my magnetic fidget gear design. Magnets are now encased, and the overall shape is more comfortable to hold and use.
The brilliant idea to use a 608 bearing for smoother action was suggested by ImpatientMaker
You will need 8 5x3mm neodymium magnets (and 608 bearing if you want to print that version). It will probably work with 5x2 magnets (or a lot of 5x1mm magnets)
Edit: Added version for 6mm magnets
