These blinking goggles use a remix of my Print-In-Place Iris Box (http://www.thingiverse.com/thing:1817180) which is a remix of emmett’s Preassembled Iris Box (http://www.thingiverse.com/thing:1811143). Right and left “eyeballs” snap into the goggles and a 3D printed spring holds them open. A discrete piece of fishing line is used to actuate the blink. Or you can also skip the spring and the fishing line and just reach up and operate each iris manually. Optionally, you can add “lenses” to enhance the look.
