Ender 3 v2 Neo 80mm mainboard fan shroud
This shroud allows you to replace the stock 40mm fan with an 80mm fan for Creality Ender 3 v2 series printers.
Since the fans on Ender 3 v2 Neo’s run on 24v, I wanted something that would let me use a 24v Sunon fan (linked below) to provide more airflow to the stepper motor controllers on the mainboard.
The Sunon fan was incredibly loud so I’d recommend getting a 12v Noctua fan and a DC buck converter (both linked below). When you install the buck converter, connect it to the 24v rail on your power supply – do not connect it to the fan header on the mainboard.
You will need longer screws to attach this to the body of the printer (I think I used 30/35mm M3 screws).
You can find the .stl file here.
