Works perfectly for the PEI plate. No risk for damage and still effective. Cheap and quick to print.

The quality is good but I found some problems with usability. - Still hard to keep the ptfe tube away from the glass. One solution could be to shorten the tube? - The tube moves inside of the clips. This may cause the same problem or worse than the tube chafing against the glass. --- I found another solution which is to put some beads on the tube (about 10 was needed). The beads are now chafing against the glass but not the tube. Also, no chafing between the tube and the beads.
