Vase Fidget Spinner

Standard fidget spinner shape, designed to be printed in vase / spiral mode, inspired by Whosawhatsis's [quick print bearing](https://www.youmagine.com/designs/quick-print-gear-bearing). I made this for printing at the Bay Area Maker Faire today (May 20, 2017), in the Bay Area Reprap Booth. Between printing all day and a bunch printed the night before, I think I gave away almost a hundred of these.

Coincidentally I met [Whosawhatsis](https://www.thingiverse.com/whosawhatsis/about) there today. He's working what looks like is going to be an awesome little printer he calls the [Cranestyle Mini](https://plus.google.com/+Whosawhatsis/posts/emCyiwZW89D).

Print with a 0.5mm extrusion width. The example prints were printed at a 0.125mm layer height and the speed set to 100mm/sec (though it was probably acceleration limited to a slower speed, total print time at those settings was 7-8 minutes). I was able to get prints down to about 3 minutes but didn't like the thick layers.
