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*.

Post printing
Uses [10mm diameter rare earth magnets*](http://amzn.to/2thAkml), which come in a variety of thicknesses - The thinner magnets allow for more configuration options, using more magnets should result in transitioning at higher speeds. [Superlube oil*](http://amzn.to/2sFivjn) or similar - I usually disassemble it after printing and a few minutes of break-in, then add one drop of superlube into each of the pivot points.
