Printrbot 1405 XL Z-axis top plate
If you have the PrinterBot 1405 with the XL upgrade, this part will give you a little more height in the Z direction. I measure about 20mm more. Large enough to print http://www.thingiverse.com/thing:308335 . You can see from the pics that the wood frame is the only thing stopping it from going higher.
Part II (ZAxisStop3.stl): Added even more room for the extruder motor. Still working on this though.
Part III (ZAxisStop4.stl): Still finding that I need to remove parts of the plate to make room for the Y axis carriage. Be sure to use a good fill % (at least 20%) to add strength since the part is getting smaller.
I included the STL and FreeCAD files. Enjoy
