PTFE Cap / Endplug

The filament box from XrControl has convinced me very much.

Check out his video about it. Unfortunately, it is only available in German: https://www.youtube.com/watch?v=6-2agpkSxcs.

However, you need two PTFE couplings for it. Since I wanted to save the second coupling, I constructed this end plug.
So that the filament is not completely pushed back into the tube, it can be put into the cap beyond the notch. The PTFE, on the other hand, is only pushed to the notch. Thus, the filament remains within reach after opening the cap.

The cap can be printed without supports. It is best to use TPU.
