The cool side is a replaceable sticker that will set you back $9 USD and is easy to replace if you’ve printed the tool that comes preloaded with the X1C and maybe the P1P. My printer came with two stickers, I just replaced one because I forgot to reinstall the screws when I changed the nozzle. When it tried to print the calibration lines, it pushed the nozzle into the build plate and engraved the sticker with the lines.
I just noticed that there is a replacement sticker for the high temp plate also.
