I made the components in Fusion and then printed them on my Ender3. The servos are driven off of an Arduino and a PWM Driver. I wrote code to procedurally animate the movement of the eyes. This video was made shortly after I go the entire mechanism working for the first time

I made this eye mech a couple years ago. The design is based on David Covarrubias’ eye mechanism covered in his “How To Make An Eye Mechanism” course from the Stan Winston School.

This proof of concept model shows the mechanisim that drives the animation. A DC motor hidden in the base drives a push rod that moves the figure. Putting the motor at an angle allows the push rod to an an elliptical path allowing the animation to look more "floaty"
