This is a head-base that can be used to build a puppet-, plushie-, robot- or a fursuit-head (costume). Ventilation holes were added for better heat-exchange. The lower jaw is movable.
I did not include the model for the ears - use a felt or foam sheet instead.
The model is scaled to hand-puppet size - rescale it if you need to. I recommend making the head at least 25cm wide for costume use.
