fan_cover for 40x40 fans
thingiverse
This cover is for fans 40 x40 mm. My fan is "MF40202V2-1000U-A99 SUNON" 40x40x20mm I use the air flow model at thingiverse "https://www.thingiverse.com/thing:4630748" "1 pc no support fang for Ender 3 V2 dual 40mm fan" The fans are not protected, so i have created a cover. For mounting i used M4 hexagon socket countersunk screw with 30 mm length
