Closely guides the filament after the hobbed gear.
To mount the bowden coupler, drill out the mounting hole to 9mm, then soak with acetone. When the plastic has softened up, carefully screw in the coupler until it's flush.
The screw the lever rides on should jam in the stepper's thread when tightened against the M3 screw that holds the motor together from the opposite side. Use thread lock for best results.
Modified versions with different bowden mounts, spring options and filament diameters coming soon!
