Blinking Iris Goggles with Battery Holder

In order to make some [Blinking Iris Goggles](http://www.thingiverse.com/thing:1833286) with [LED rings](https://www.sparkfun.com/products/12664) in the eyes, I'll need to supply it with power. Since there are already two strands of fishing line hanging from the goggles (to actuate the blinking), I decided to put [a battery](https://www.sparkfun.com/products/341) holder right on the goggles instead of having a wire going off into a pocket somewhere. I also wanted a way to detect actuation of the blink. I decided the best way to do this was have a [small neodymium magnet](https://www.sparkfun.com/products/8644) glued to the rotating part of one of the eyes, and have it come near a [reed switch](https://www.sparkfun.com/products/8642) which could be mounted to the battery box. I remixed the *Right Eyeball* file so it has a magnet holder that will accept a 5mm x 3mm magnet. The one in [the video](https://www.youtube.com/watch?v=0q_jhrTBqlE) is a 4mm x 2mm.
