The idea was to make those flexible bracelets into a type of gyro spinner.

I used it as practice to make these objects without cutter or union objects. I use these pretty habitually, but vertex manipulation and other Blender tools can produce results also.

The gyro spinner doesn’t work. The pieces fit, but getting it to spin seems like a challenge above my paygrade. The objects when wrapped have loose ends and don’t approximate a circle neatly enough to act as a gyro.
