This is a head base that can be used to build a puppet-, plushie- or robot-head.
I included some parts in the mesh that are only needed for a hand puppet (like the surface at the top of the lower jaw). For costume use, I normally leave holes in the head to make it lighter and give it more ventilation.
If you scale it up it can be used to make a costume (fursuit head), but some modifications will be needed. Fake fur can be glued on.
