Expanded the lightbox to fill most of the P1 and X1 series printer bed. Refer to RevHazlett's original design for hardware links and youtube tutorials on how to build and assemble.

I also filleted the inside corner of the lid to improve strength. Before, I had the lid top break with as little as a few pounds applied. With the added fillet, the lid now holds 15+ lbs of weight.

I added an optional second hole for another power jack. This is for the ability to daisy chain signs together if you have multiple signs near each other. The current draw is heavily dependant on the RGB pattern you use. It can range from 120mA to 1.4A if it is solid white with my 5v 2A power supply. Plan accordingly to how many signs you will be daisy chaining and purchase a large enough power supply.
