Extruder for FolgerTech modification

thingiverse

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. You will need the original models to import and work with. This is minimal changes needed to use the original fixtures. However the lever itself and lever cap can be changed to be less requiring to the printing process (e.g. to eliminate thin walls) as the volume this lever can take is limited merely by "looks good", e.g. you can expand in at least two directions to make it easier to print and easier to assemble.
