Spinning top

I got tired of ads for $100 titanium spinning tops, so I made my own for $1. I got one to spin for 90 seconds on my laminate kitchen bench. It can also spin upside down, if you have the right knack to set it going.

Because of the slope of the "top" surface (no pun intended), the infill can show through the shell layers. That's why I suggest fine layer height and maybe 4 or 5 top layers.
