Have you ever had small pieces of consumables break off in your PTFE Bowden tube?

I designed this adapter to connect to a vacuum cleaner, which uses suction to remove small pieces of broken consumables.

Just connect it to one end of the pipe and place it in the suction section.

It is suitable for small pieces of consumables, but it is more difficult to remove larger pieces of consumables.

It is suitable for vacuum cleaners with a diameter of 31.5mm.

This component can be printed without the need for support.

If you have any ideas on how to make it better, please let me know.
