Light up hedron (pocket version!)

Hi!
This is a 4.5 x 2.16 x 1.04 inch (110 x 55 x 26.5 mm), "hedron shard", modeled from Wizards of the Coast's Khans of Tarkir trailer (https://www.youtube.com/watch?v=BIC1M_eKagk), see attached screen capture. The piece itself has a hole for mounting on the top. The body piece has a slot made for a coin cell with attached, easy-to-operate string LED lights (I got mine from Adafruit! http://www.adafruit.com/products/895 or http://tinyurl.com/pfy5hjn if you're impatient about shipping).
