Printrbot Simple Metal - Printbed Upgrade

UPDATE
**So I finally got around to more tweaking, Swapped out the power supply for an up-cycled ATX power supply. Hooked up the power switch, voltage and current meters and re-did the wiring completely which neatened things up a little.
hope you guys enjoy :)

UPDATE
**I've modified the swivel feet to allow the printrbot to tilt onto its side. no more need to awkwardly balance the printer upside down in order to get to the board.**
