Extruder for FolgerTech modification

This is a modification for FolgerTech extruder to include bearing mounts into model. This extruder requires further modification to use original bolts and screws (the mounting hole of the lever needs to be bigger to accommodate the bronze spacer that is in original extruder, and the bolt cap rest needs to be modified for the cylindric cap.
As this extruder didn't work for me (original spring tension is too strong and motor is skipping instead of extruding), I include the OpenScad file I used.
