It looks like a typical thinkpad rubber back, but with the x1's "carbon fiber" design cutting through it with a wide diagonal line. Google only gives standard rubber backs. Anyone have any idea what this version of the design is called?
A couple minutes after posting, I also ran the image through google lens. It only shows custom carbon fiber wraps and images of X1 thinkpads. Here the carbon fiber design is only in a diagonal line, what's that design called?
