I made a pivot arm mount to position the standard pivoting filament arm, off of the extrusion without the folded arm breaking the plane of the printer frame. The purpose behind doing this was part of a series of small modifications to clear the printer frame of obstructions top facilitate attaching a low profile enclosure. Anyways attached is the stl for printing it, and some pictures of the resulting mount. This mod requires a short M5 flathead bolt, and a M5 nut, in addition to using two M5 T nuts, and two short bolts to mount to the frame.
This thing is also up on thingiverse with the OpenSCAD model (http://www.thingiverse.com/thing:1034159/#files)
Certainly a lower profile pivot is possible, if the arm is modified, as well. I might work on that as another option.
