I finally corrected the magnet size by measuring it a second time. I made extra space where the soldered wire would wrap so the solder blob would not interfere. Lastly, I sunk the fastening hardware so the top and bottom would be flat.
I printed the REV20 spinner and installed the brass bolts and wire loops. The magnets fit right into their spots, and I sandwiched the halves together and added nuts to secure everything.
I tried hand-bending long wire loops that would reach from the spinner's center to an axle holder with wire guides at the top. It was too difficult to shape the wires correctly by hand, so I stopped before something else broke.
I made a wire-bending jig to facilitate the next steps. If it works, I can add more advanced features in subsequent iterations.
The wire-bending jig worked well enough to make a cage-like brass structure, but the rods were still too stiff to create significant flexibility between the hub and rim.
I ordered flexible printer resin and programmed spokes to go between the hub and rim of the spinner. I can quickly change the number, width, and thickness. Each time I run the printer, I can test three configurations and find one that is tough and flexible.
The rest of the summary posts have been arranged by date.
