This head base was made to build a hand puppet head for an animatronic fantasy bird creature. The lower jaw is movable. I included the files for the movable eyes and eyelids - they are compatible with my other eyelid mechanisms (if you do not want to print the eyes you can alternatively ist 4cm diameter ping pong balls). The head is meant to be printed with lightweight PLA.
The files are all scaled to make a 16cm wide hand puppet head.
