A new x-carriage for my Printrbot+. I wanted to have a little more room for a ducted fan (haven't figured it out yet) around the extruder, and the lasercut x-carriage was a little cramped. So... here's this one.
Update: I've extended the deck enough to accept this part http://www.thingiverse.com/thing:25473 and it fits just fine with slight modification to the cooling duct. Also, I've renamed this part to extruder mount as it is not the entire carriage.
Print it, clean up the openings, and fit it onto your Printrbot+/LC
If you want it to work with the fan duct found at http://www.thingiverse.com/thing:25473 then print out the pbplus_mount_update and put it all together.
