This is the upgraded 265C higher temp nozzle for the FlashForge Adventurer 3.

It can be used instead of the standard 240C temperature nozzles in all compatible FlashForge adverturer 3 3d printers.

This is also an easy switch nozzle, they look & work exactly like the previous 240C nozzle with the added advantage of printing to a slightly higher temperture.
This is unique system allows you to quickly switch the nozzle, & heater block without any assembly.
Just press the clamps on the sides of the head to push this assembly out, & then insert a new one in.
