What is this ? Part not used question?

Today I was looking for some spare screws in the box which the printer came in. I know there are some plastic parts left over since Velleman send some parts for a second extruder etc.

Look at manuals.velleman.eu/article.php?id=4 subkit 15 (Plastic parts) bag D. The part at the very bottom of bag D are two small “guides” for filament.
For some reason unknown I have two of these left over and I can not recall using it.

Where does it go or is it a leftover ?

Hey
Thats for/of the k8200

look for the extruder on this page:

I was worried there for a short time.
