Poke an eye out with one of your experiments? Harness the awesome power of thermoplastic fusion to print a microprocessor powered bionic replacement! It won’t help your vision much, but no one will doubt your mad scientist cred. The Bionic Eye Module is a 46mm 3D-printed servo-powered electro-mechanical eyeball sized to fit into standard 50mm goggles. It uses 2 sub-micro sized servos and an Adafruit Trinket to create that creepy nervous tic.
