This tool lets you remove the PTFE tube from the toolhead in one of two ways:

Method 1)

Push the rounded side into the top of the toolhead (see pictures) and pull the tube out. The advantage of this method: You don't need to remove the toolhead cover.

Method 2)

Insert the little fork between the PTFE holder and the PTFE connector (see pictures), push the tool forward and pull the tube out. You need to remove the toolhead cover for this, but it's easier to see where you are pushing.

Use whichever method you prefer, this tool enables you to choose depending on the situation or your preferences.

If you like this tool and also happen to be a fan of the BaBo organizer system by Willi3D, I designed an insert for this tool which can be found here.
