Summary

The painted one has been modified with my 3d Pen. It was painted at 3 times size on the body and I shrunk the head to .3.
The smaller one is fresh off the printer at 2 times size and a head at .2 will fit.
I recommend a high infill so the small bits don't break.
I attached the head with the 3d pen.
The head and body where sculpted in Oculus Medium.
If you need the head it's in my library of stuff.
