Replace the clamp clip

The clamp clip locks the Bowden tube in place. Without the clamp clip, the tube coupling collets which hold Bowden tube will move during prints, especially during retractions, which can negatively impact print quality.

If the clamp clip breaks or gets lost, you will need to replace it. The following steps describe how to correctly install the clamp clip:

Parts required:

  • 1 or 2x 1071 Clamp clip

Tools required:

  • None


  • 2 minutes


1. Remove the old clamp clip

  • Place the print head in the front-right corner.
  • Use your fingernail to remove the old clamp clip from the tube coupling collet.
