I made the 3d-models for the head-base for this fursuit head and printed them in Taulman Nylon with my Flashforge Creator 3d-printer. The head was printed in 618 Nylon, the eyelids in Taulman Bridge Nylon. The parts were assembled using Plaast (http://www.plaast.de/) - the teeth were made by hand.

I use Bowden-cables to control the eyelid and ear movement - no electronics, just pushing and pulling on the cable. This is a very simple and cheap method to create animatronics.

There is a video that shows the mechanics: https://www.youtube.com/watch?v=7BHXK4AS5YQ

The fur-cover can be detached from the head - sew-on-snaps hold it in place.
The nose is detachable too.

I changed several things after I made this fursuit. The eyes and eyebrows were replaced.
