Bowden Tube Retainer Clips

thingiverse

Insert a clip between the release ring and fitting body to secure the tube in place. This helps minimize tube movement during retraction, allowing for potentially shorter retraction lengths. Various thicknesses are available; use the thickest one that fits comfortably. These clips should work with any 4 mm O.D Bowden tube fittings, including those on your Ender-2 printer.
