Summary

Just a stupid idea I had during some days off from work...

Instructions

The STL file will create an object with a total height of ~12cm.
If not scaled up, the diameters of the fingers are only ~2..4mm, in this case.

I tuned the orientation of the skull to the point where a minimum of (high) support structures are required.

Good luck!

PSSST:
If you wonder about the red dots in the rendered image:
They are only there to outsmart the image upload crop feature.

Never understood why the Thingiverse folks used that...
