PTFE tube connector nut

I needed to secure the coupling of the PTFE tube to the box with the filament, and this is how this simple model was created.

A tube with an outer diameter of 4 mm and a coupling with an M6 thread are required.

I created a thread in the model with a tap. It works beautifully.

Printed from PLA.

As usual, here is OnShape model, modify as you wish or as you need.

You can also use the model for guiding the tube to the extruder for the MK3S+, here.

And also these material markers to put on the tube to quickly know what is inside the tube, here.
