This is a head-base that can be used to build a puppet-, plushie-, robot- or a fursuit-head (costume). I did add some ventilation holes, that can also be used to attach fur. The lower jaw is movable.
The model is scaled for costume size (it's sized for my own head - I have a small head) - rescale it if you need to. The current size is for small heads.
Update: I added a second version without the holes (the files with "noholes" in the name) - some people want to use it without fur or make it light up with LEDs. I do not recommend using the version without holes for a fursuit.
