Hold your PTFE Bowden tubing tight in the collet with these collet clips
Easily identify filament diameter with color coded clips
Red - 2.85mm filament
These collet clips are designed to eliminate the backlash created by the collet in our embedded bowden couplings. The collet clip should be pushed under the plastic collar, where it stops any back and forth movement of PTFE tubing when extruding and retracting. This greatly improves the precision of the HotEnd.
