Toy Spinning Top - tercera versión modelo 3d

This is my 3rd version of a basic toy spinning top, and slightly larger than the first two.  It is a very simple design, but has some unusual properties compared to a conventional toy spinning top.

It is designed to be easily printable without the need for support materials.  It doesn't have a handle on the top, but can be spun by placing it between the thumb and pointer finger with the flywheel part facing upwards, and "flicking" it with the fingers.  It can also be spun by placing it between the thumb of one hand and the pointer finger of the other hand and "flicking" it that way.
