Magnetic gear toy! Customizable with OpenSCAD. I used these magnets: https://www.amazon.com/gp/product/B07Y4SGWBD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 They are nominally 10mm in diameter and 3mm thick. If you want to use differently sized magnets, you'll need to adjust the magnet size in the .scad file.
