Battery Holder & Infinity Stone for Eye of Agamotto

I wanted to light up the Eye of Agamotto by Laci Legath (http://www.thingiverse.com/thing:3380529) with an LED and watch battery.

The backing and green stone are custom designed to work with this pendant and the battery holder below. The switch is accessible through a hole in the back piece.

I had to drill a hole in the Laci's pendant so the LED can pass through into the Infinity Stone which I of course printed in green.
