This saves valuable space on your print head and improves heat dissipation efficiency compared to plastic extruder designs.\u003c\/p\u003e\n\u003ch4\u003eQ: What is included in Set 3 and Set 4, and can I request a different nozzle size?\u003c\/h4\u003e\n\u003cp\u003eA: Set 3 includes the extruder, a 23mm stepper motor, and a V6 Hotend Kit (with an all-metal NF V6-Crazy heatbreak and default 0.4mm nozzle). Set 4 replaces the V6 hotend with a Volcanic Hotend Kit for high-flow printing.
