This is a 3d-printable head-base that can be used to build a puppet-, plushie-, robot- or a fursuit-head. Ventilation holes were added for better heat-exchange. The lower jaw is movable.
I did include the model for the ears, but I do not recommend using those (you do not want rigid ears on a costume) - use a felt or foam sheet instead.
The model is scaled to costume size - rescale it if you need to. The current size is for larger heads.
