UP Plus Modified Extruder

Based off of Drew Petitclerc's UP! Extruder Modification

Modified the existing Extruder to fit an UP Plus. I added the the mounts for the fan shroud and the fan itself. I also modified the heater board mount to fit the new board. I printed everything out of PLA on the UP including the Pressure arm and the holding block and have about 20 hours printing on them so far. Instead of using a Spring plunger i substituted a Screw and Nut which i glued to the extruder and then found a pen spring of suitable size. This allows me to change the pressure quiet easily which has com in handy while printing Flexible filament so far.

This is still a WORK IN PROGRESS as i did have to remove some material with a dremel to make everything operate smoothly. I will be updating theSTL to reflect these changes soon.
