Magnetic Tri Mini Fidget Spinner for smaller hands

I printed out a cool spinner, but it was too large for the hands of a 7 year old. I happened to have some N42 cylindrical neodymium magnets and smaller-sized bearings, R4Z, so I built them with what I had on hand.

I included a pic of these bearings vs the more-common 608z, this project does NOT work with 608z bearings!

USE CAUTION WITH MAGNETS!!!!
