I took the door off my X1C recently to keep from breaking the glass while I was replacing a part. During the process, I ripped one of the rubber gaskets that isolates the glass from the metal brackets. Print four in TPU for a spare or replacements.
I was a little frustrated when Bambu said that they couldn't sell me replacement grommets for the door, given how easily the one ripped, but this was exactly what I needed.
They printed perfectly, I just installed them, and they fit perfectly.
