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 ears are a separate model, because
I made these as a template for cutting foam or felt. Having rigid ears on a costume is not a good idea. https://www.thingiverse.com/thing:3466259
The model is scaled for costume size - rescale it if you need to.
