Solidoodle Hot Head Mount + Filament Feed

I like this idea, and I noticed huge improvement on my ToM using the minimalist MK7 extruder, but I am not sure I see how this will gain head space above the extruder in the Solidoodle. Nonetheless, when changing filament, I much prefer pushing on an ABS lever rather than that acrylic sandwich (especially since I can re-print the minimalist extruder pieces if needed).

When you start putting this together note that you should install the hot-head first into the mount then install that on the printer. Its a bit tricky to hold those two bottom nuts to fasten the screws from back so be patient.
I tested this and it works great for me so far.
Filament feed is based on thingiverse.com/thing:15718 Minimalistic Mk7 replacement but I have modified it so it fits Solidoodle and so it provides enough tension with the Solidoodle spring and most importantly so it clears the Solidoodle enclosure.
IMPORTANT: If you do this mod make sure to screw down the Z-axis screw in the back since this mod might slightly lower the hot head so when you try it, it might crash into the bed. So just note that you need to do Z-axis zeroing in and to be on safe side screw down that screw before moving hot head.
UPDATE 11-09-2012 - I have changed the extruder design so it uses screw instead of spring. File name for this new part is EXTRUDER5.stl I have found that using the Solidoodle spring does not provide enough tension for smooth feeding of filament. Screw I used is re-used from acrylic Solidoodle jig-saw puzzle ;-)
