About this model

Remix of a previous spinner that required a ceramic bearing. This one doesn't spin as long, but it should go for 30-45 seconds without too much effort. It accelerates more than the previous version since the magnets have more travel without the bearing to get in the way. It requires a few flicks to spin it up since it slows down when the magnets move to the outer position. Inspired by example prints I saw from whosawhatsis's book, 3D Printed Science Projects.
