1.75mm direct drive bowden extruder with tubing guide
thingiverse
This is an extruder engineered for use with a tooth gear measuring 11mm, it has two distinct versions - one equipped with a tubing guide that allows insertion of a piece of PTFE tubing to direct the filament into a push-fit connector and another without this feature. It's well-suited for handling soft and flexible filaments, and is also extremely simple to assemble and load the filament. The arm features both the tubing guide and connector. Spring tension can be adjusted with a screw. Calculated step/mm equals 92.59923; however, an error was made by using 95.599 instead, resulting in perfect operation.
