Bowden extruder for 1.75mm filament and 1/8" push fit coupling (used for 4mm OD tubing)
myminifactory
This is a custom build based on Carl Feniak's extruder design but with key modifications for 1.75mm filament and a larger bore to accommodate a push-fit coupling suitable for Bowden extruders. The coupling type used in this design is the "4mm OD Tubing to 1/8" Male Thread - Quick Connect for Bowden Extruder Tubing". Update: After making some adjustments, the opening now securely screws into place without any issues straight off the printer, and the filament entrance has been tapered for smoother flow.
