40mm Extruder Fan Blade Replacement (Ender 3/Ender 3 Pro)
thingiverse
I accidentaly broke one of my Ender 3 Pro's fan blades so I made a replacement. I created 2 models; one with 7 blades and one with 9 blades. To install, just remove the other remaining blades and sand it a bit. After that, it should fit in tight. This should fit any 40mm fan that has a center hub diameter of 21.5mm. Also, print it front facing down on the bed. -Updated to v2- Issue fixed wherein the blades are printed at the 2nd layer which makes it not stick to the bed properly
