I heard this fall out of the chute on my X1C during a job. One side has an adhesive on it.
What is it and how should I replace it?
From the shute in the rear
Found this reddit thread about it.
Should I try sticking it back on, or should I just stick some kapton tape in the same place instead? That wouldn’t have an edge for the purge to get caught on.
Some filaments stick pretty good to Kapton. I used to use Kapton tape on my Makerbot Replicator build plate, back in the day (when 3D printers were so old they had cranks on the side you had to turn to make them work 
).
Gotta think BBL would have gone with Kapton or Delrin instead of the metal plate, if that’d have worked better. The metal plate adds cost/complexity. Yeah, it’s only pennies. But good design teams care about pennies.
I’d glue the metal piece back in place. A little dab of silicon adhesive, maybe.

Good to know!
I guess I’ll try to round off the edges a bit before sticking it back in place, too.
