Extruder E3D type bowden coupler clip shim

This is a remixed version of the extruder multi clip but smaller to suit the E3D bowden locking ring fitting. This prevents the locking ring from moving in and out of the extruder/hotend which prevents poor filament control especially when retracting/unretracting.

Slide the clip into place before inserting the bowden tube and you'll have a tight fit with no play from the start. Unclip it to remove your bowden tube.
