  • Extruder fan

Extruder and gear cooling fan mount designed specifically for the Tuzhu A-series printers, featuring snap-fit installation that ensures a damage-free setup and can be printed as a single part.

The fan is controlled by a temperature‑sensing switch: it activates only when the extruder heats up, providing effective cooling, and automatically shuts off once the temperature drops.

Required components:

4010 cooling fan, temperature‑control switch (model KSD9700, normally open at 40°C), M3–12 screws (2 or 4 pieces), and one 4‑pin power cable for AMS interface power supply.
