Other handed direct drive 1.75mm bowden extruder. Also use for c

Description

Summary My second version direct drive extruder, I got the handedness incorrect for my mounting on my first one. This version has a funnel in the arm that you can fit a small sponge or cloth in to clean the filament as it goes in. I also curved the bearing end of the arm slightly to allow it to grip even tighter. If you use nylon filament and a good stiff spring it can drive curtains. Quietly.

Note that the bearing cavity has 0.75mm thick supports designed in that should be carefully removed first with sharp side cutters.
