The Ender 2 Pro has a 50 mm always on fan in the mainboard compartment. The fan is on the noisy side. With the new Noctua 40mm 24v fans available, it would be good candidates for replacing the 50mm.
This part was designed to use the current 50mm 2 post mounts, reusing the screws, and the supplied screws from Noctua to screw into the 40mm fan.
This part was printed with the posts facing up, PETG for some heat tolerance, 3 walls, 4 top/bottoms, 40% infill, and 0.2-layer height.
Used the included 2 pin adapter with the Noctua fan kit to connect to the mainboard wires.
This was designed for the Ender 2 Pro, but the spacing are for a 50mm fan, so this could be used elsewhere depending on the fit.
The author marked this model as their own original creation.
