Bobblehand - the Italian Bobblehead

Ma che dici?

I've wanted to make one of these since the first time I saw the incredibly smart bobbleheads by 3D Printy. This contest was the motivation I needed.

The hand comes from this model I've found on Thingiverse. The original 3D scan is a little messy, so I've cleaned it up a bit using blender. 
The spring is a little beefier than the original, because the hand is a little top heavy. Print the hand with low infill, to save on weight.
