Is it possible to get a replacement nozzle for the ZSYong 2IN1 mix print head? Do they have different size nozzles by chance? Also, the regular ZSYong 2IN1 nozzle (non-mix version) comes with a silicone sock, but the MIX nozzle doesn’t. I’ve had bad luck with PID tuning on hot ends that didn’t have a silicone sock in the past. Does a sock exist for the MIX nozzle as well?
