It worked!
I added a pair of ball bearings with double-sided tape to the spinner tabs since it would be the easiest to reverse if it failed. I reassembled the spinner and installed it in the shell. The bearing was lower than the spinner's bottom, which was a disadvantage of my simple tab design, but it made it clear to see. I lowered the M3 threaded rod in the bottom to meet the bearing, and I could feel it when it passed over and clicked when I shook it!
This design taught me a lot and has potential for miniaturization, but the inertia led to a lot of swinging back and forth, and the flexible resin was hard to control. I want to try a different design that uses the previous cylindrical magnets.
