Anycubic Kobra blower fan adapter / 40mm fan

thingiverse

A blower fan adapter for better colling and hugely reduced noise which was the main motivation for this. Designed for any 40x10mm radial fan. This design is basically without any compromises so try it out! It is fast to print as well! Also stealthy and not visible from the outside. It more or less requires the really great fan duct from jimsterdelux: https://www.thingiverse.com/thing:5370436 but could be modified for the original one as well. You can use 2 of the original screws to screw in the adapter. Also you can screw in the fan from the bottom but it is designed to be a press fit so dont bother. Keep in mind that the voltage on the fan 1 and 2 ports is 24V so you need either a 24V fan or a series resistor to get the voltage down to your specific one. If you want a guide for the resistor comment down below. I usually reply in 1 day. I recommend the original Anycubic Hotend Fan for beginners. Even better is the NF-A4x10 FLX with a 330Ohm(max. speed) or 470Ohm resistor (1W rating) soldered into the red wire (positive +). It even comes with the right adapter for the connector and is impossible to hear from 1m away.
