5 PTFE Tube Markers for multi filament use (MMU / XL / ..)

Very simple:

Markers which can be added to multiple PTFE tubes to distinguish them. This is useful for an MMU unit, an XL or other multi color printer and / or a dryer.

In my case it is marking the exits of the Sunlu S4 exits before they enter the XL filament sensor.

To keep the PTFE tube from wandering upon push and pulls, it is very tight. You can “screw” it onto the pipe. That way it will remain in place when inserting or pulling the filament.

There are two sets: 4.1(mm) - which is really tight, but will then not budge easily, and 4.4(mm) which is much easier movable.

Drag the two files (cube & font) onto the slicer and give them separate colors.
