Raise3D Fan Mod (Extra Gcode Controlled Fan)

myminifactory

I created a custom fan mod for my Raise3D N2 Plus Dual, which I believe should fit all N series models. My goal was to add a 40 mm fan that could be controlled via gcode to regulate airflow on the printed model. In this setup, the stock 35 mm fans only cool the cold end, while an additional 40 mm fan positioned in front cools the printed material under both nozzles. To make this work, simply connect the 40 mm 12V fan to the extruder board next to the two "always on" fans for the cold end. It's essential to ensure that the heating elements do not come into contact with the duct - I had to adjust mine slightly to the back of the hotend and it fit perfectly. I've included STL files and an Ideamaker file for the 40 mm duct, which features added support.
