Glad you asked. I have made a couple of wooden ones with inlayed magnets. Was not too difficult, just need a drill press and drill bit matching the barings you are using. Video is here: https://youtu.be/WXl7mTaunx4
Sounds like you have some kids at home! Check out the fidget spinners @AndrewJones made - https://www.workshop.com.au/t5/Interiors/My-video-about-making-the-fridge-magnet-fidget-spinners/m-p... Andrew made magnetic versions so they can be stuck on the fridge.
Have any other community members made them?
