This is a blow top! You spin it, then blow on it from the top to speed it up and control it's movement.(Note, it only spins in one direction. If you want a left-handed top, mirror it prior to printing)

Blowing on the left side makes it go away from you, the far side makes it go right, the right side makes it go towards you, and the bottom side makes it go left.

Print with the rounded side down, and with supports. I found that if I had supports for 70 degree angles, it would support the bottom of the fins without mucking up the sides of them.

The file is hollowed already, so print it on 100% infill.(1.2mm walls).
