Hi everyone,
While trying to solve a problem (Hello Everyone : Any Idea? - #3 by Neant)
I may have created an other one.
I was following a tutorial to fix a problem I have noticed that a small piece of the X1C felt down.
Do you kown were this small square is coming from ?
Thank you.

Its from your “exit chute”, its should be stuck but often comes off.
