Air Powered Top

I a helical air-powered top, designed to spin when you blow on it. (a straw may help) Not a completely original design, as the basic idea came from Make Anything's Galactop, but the file and open top design are of my own making. Should print best upside down with rafting and very light support material. There is a hole almost all the way through the center to insert a pin or nail if the point wears out.
