I modified it to use 608 ball bearings and 8mm x 3mm magnets. I also designed it with the posts separate so this can be easily printed without supports. You'll just need some super glue when putting the posts and magnets in place.

Print two posts. Place the bearings on the end of the posts and put a magnet inside of each bearing.
