Aluminum Printruder Variation
Description
This is notionally based on the Printruder II extruder body. I like the basic design, but I had problems with filament getting kinked in the empty air below the drive gear. I was having too many issues getting the extruder to work reliably to be able to print a new modified one with less open space. Since I also have a CNC mill and a tap&die kit, I just designed up and carved a new extruder head out of Aluminum. It allowed me to have tighter tolerances, and it seems to work pretty well with my home-built Mk5-alike worm gear. This is designed to work with an 11mm outer diam worm gear drive wheel.
