Anycubic Kobra 2 Max and Anycubic ACE Pro

This is an Anycubic Kobra 2 Max 3D printer paired with an Anycubic ACE Pro filament multi-colour system. Bought it a few months ago as a backup printer, needs a new Nozzel I just cant be bothered to replace the nozzle and fight with the printer. Since I cannot prove it is in perfect working condition I will be willing to write up an agreement stating if the nozzel is replaced and the printer does not work Perfectly I will refund the money on return if the printer, I am willing to sign this agreement and allow the buyer to take a photo of my personal Government ID for their own Records!
