Description
Remix of a previous spinner, but this one doesn't need a ceramic bearing. It still uses 10mm rare earth magnets*. 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. Similar to the way it speeds up as it slows down, it also slows down as it speeds up so it needs one or two more flicks to speed it up after the magnets move to the outer position.
Inspired by example prints I saw from whosawhatsis's book, 3D Printed Science Projects* when I was at the Maker Faire.
