In the past few years, we have covered plenty of awesome 3D printed Marvel Universe inspired items here. This 3D printed Eye of Agamotto is also worth a look. It was made with a Zortrax m200 using Z-Ultrat filament. This Eye of Agamotto has a light inside and can be opened or closed.
You can close or open the eye by rotating the rear piece. Black_Ram_Industries has shared more information about this here.
