Summary

These are the parts for making an animatronic eye using an standard 4cm Ping Pong ball. Beside the printed parts, it needs a long metal wire (6cm) as the central Y axis, and 2 small metal wires for the eyelid X axis.
I used one of my old bike wheel spokes since those were hard enough and had a lot. For the eyelids I used small wood nails with the points cut off.
