Spin one of the rings and the other one will spin with it if you arrange the magnets right. Though it didn’t take considerable effort to design, it feels like a (useless) product and I like fidgeting with it, hence it received its own panel/description. The stand is removable to support modularity and potential future expansion. It was designed for 10x10x10mm magnet cubes, but consider scaling to 105% in your slicer before printing.

I’ve been fascinated by magnets even since I was a kid, but it only turned into experimentation when I came across a video about Halbach arrays. I wondered whether I could come up with an unassisted levitation design, so I got myself an FLSUN Q5 delta 3D printer, a few dozens of magnetic cubes and learned how to create models in TinkerCad. Even though I did not succeed in my initial plan, I still ended up with some fun magnetic toys I can show my guests and a bunch of rock-paper-scissors dices for boardgames.
