PTFE Tube Clamp for BMG Extruder

thingiverse

This PTFE tube clamp can help to get more consistent extrusion and better retractions. It was designed for the BMG-style extruder clone by Trianglelab. But it might work just as well for other PTFE couplings. In this video I show that without the clamp, several millimeters of retraction movement are lost because the PTFE tube moves: https://www.youtube.com/watch?v=1SeqcXiOh5Q With the clamp installed, there is almost zero movement of the tube, resulting in more precise retractions.
