That looks pretty convincing! So I will drill that hole and try the same.
@rovster May I ask how much (full 360degree) turns of the screw were required to achieve the result you’ve shown above? And now the silly bit… in which direction did you turn? At first I thought about counter-clockwise to loose the screw, but looking at this photo I wonder if tightening the screw would pull the string away from the extruder.
