hinged dual x carriage for qu-bd mbe

This is a work in progress, and my first thing. The qu-bd model came from here: http://www.thingiverse.com/thing:51916

Gonna try to sneak a test print at work tomorrow and check the fit. I need to come up with a way to hold the extruders down when closed.

I added the sketchup model, feel free to improve on this design, or tell me why you think it's no good. Thanks!

Update 02.25.13 proof of concept looks good, needs some tweaks. Gonna add a small cylinder across all 3 hinges at the rear
