Open beam 3d printer

my home built Openbeam extrusion based reprap 3d printer. Most of the structural members are based on this very nice design

the extruder is a direct drive soldioodle style Mk5 an can be found here:

I had to create my own x carriage to mount the new extruder. Electronics are the standard Adruino Mega/Ramps 1.4 setup everyone else seems to be using. The hot end is an all metal E3D.
