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.

Have a look at my project page here:
https://hackaday.io/project/7083-printrbot-simple-metal-bed-upgrade

I had the new printbed cut from 3mm and 4mm Aluminium and tapped the holes in the 3mm frame to make things easier.

The new print volume is 270mm × 205mm × 140mm

the A3 sized .pdf files are also uploaded.

as for the parts to be printed, i mostly printed with 0.2mm layers and 15% infill, 20% for some structural parts. I'm still updating as i go along, the parts here already have some of the errors fixed.

Enjoy
