Animatronic Eyeball with Manual Controls

This is an eyeball with left/right, and up/down manual controls.
It uses a ball and socket joint that snaps together to allow eye movement within a socket. Strings are attached to the inside of the eye from within the control box and through the neck which allow you to make the eyeball look around by turning the knobs.
