Summary

70mm round eyeballs for rod puppet / mech

Best printed in ABS so you can make it nice and smooth.

Front eyeball also has option for recess to suit a 38mm ROUND Clear Glass Dome Cabochon with the idea to put a light and image of the iris behind it.

Rear indent for an 6mm springs. See example photo for better understanding.

Added side and middle mounts, added rear mech.

Rear mech is designed to have 6mm springs inserted, they are then attached to back of the eyes.

Side and middle mounts are for 6mm rod.

Eyelids were made to fit my puppets curve, you may need to change yours.
