Twin Tops is my rendition of Grand Illusions "Magneturn" (link to video below). Spinning one top induces motion in the other thanks to magnets.   Video of prototype is here:  https://www.youtube.com/watch?v=woXns1lunyA.   Video of Grand Illusions "Magneturn" is here:  https://www.youtube.com/watch?v=zllYJokkvV4&t=10s.   You will need to purchase 10 neodymium disk magnets 12mm in diameter and 3mm thick.   Designed using Fusion 360, Sliced using Cura 2.3.1, and printed in PLA on an Ultimaker 3 Extended.   Printing and Assembly.   Printed on an Ultimaker 3 Extended at .1mm resolution and 50% infill.   In order to correctly orient the magnets, I started by stacking all 10 magnets together, then one by one placing an "X" on the topmost magnet using an indelible ink pen, sliding that magnet off the stack, then repeat the process with the next magnet until all 10 magnets are marked.   Position the Top "arm" magnets into the 6 arms with the "X" facing outward.   Position the Base "tower" magnets into the towers with the "X" facing upward.   Finally, position the Top "center" magnets into the top with the "X" facing downward (the "X" must be visible when looking into the top).   Slide the tops onto the Base towers and spin.
