Movable puppet eye and eyelid

These are my 3d-models for movable puppet eyes and eyelids. The eye was designed for a resin printer - if you print it with an FDM-printer you'll have to do a lot of sanding to get the surface smooth. The 3d-printed resin eye is painted with white spray paint (because some white UV-resins get yellow over time) and acrylic markers, the pupil and iris are filled with transparent 2-component resin.

I print the other parts on my FDM-printer with 0.2mm layer height, wall thickness 3, 10% infill, no supports.

The eye can be exchanged with a ping pong ball (if you prefer painted on eyes) with a 4cm diameter.

The lever in the back of the eyelid can be operated with a Boden-cable or servo-motor.

You do not have to print all the parts - I added several versions of the eyelids that differ in the placement of the lever. There are 2 versions of the eye (one with a round, one with a slit pupil). The puppet_eye_backplate is optional.
