Needed a head model that was hollow so I could fill it. Not sure this will be useful to anyone else but here yall go.
Printing with 3 wall results in an exceptionally sturdy head (I could football spike this thing into the ground and it'll survive) but uses quite a bit of filament. 2 walls should be more than sturdy enough and will save some material.
At default size the hole in the base was about the same size as opening my mouth all the way, just a little too small to fit my fist in. I guess if you want actual measurements it's like 63mm.
