My son wanted to be a spider for Halloween. I wanted to add some unique touches to his costume so I 3d printed some LED lit eyes. I modeled them in Fusion 360 and printed them using my dual extruder MakerGear M2, a dual extruder 3d printer is not required though.
The eye can be lit with a 3mm LED and a watch battery, no other electronics needed.
I liked them so much I made a creepier version for myself. The base can be sewn to fabric using the recesses in the base. The base was dual extruded with black ABS and HIPS as a support material which was later dissolved away. I uploaded the models to Thingiverse and created some YouTube videos below. Shiny version shown was finished with Smooth-On XTC-3d.

Modeling the Eyes in Fusion 360:
I used Spheres and the Combine features to create the majority of the eye. Fusion 360 is great free CAD software and is quiet powerful. Be sure to check it out.
3d printer - MakerGear M2 dual extruder is what I used (This link is for single extruder version, Amazon doesn't sell the dual extruder version)
