Dual Extruder for 1405 300mm No Sag, Printrbot Simple

This is a mod of http://www.thingiverse.com/thing:372467 by iamjonlawrence, specifically the part labeled 1405AlExtruderFront-Short-2014-06-24.STL. All I really did was slice the extruder section out then realign it back to an uncut part, mirroring the extruder location. In theory this should work as a fully functional dual extruder Printrbot simple (requiring another extruder, extrudrboard, etc.). No guarantees as I haven't tested it yet.

Edit: I've printed it (with supports, pictures uploaded) and physically it seems strong enough to work. I've also added some pictures of a Printrbot Aluminum extruder + motor attached to the newly added extruder section. If I get the time I'll try it out, in the mean time if anyone makes one and uses it successfully please let me know!
