Update 3/3/2018 - Check out more options in my collection: https://www.thingiverse.com/thing:2813669 Easy 80mm Fan Grille. I searched for many excellent fan grille designs, but none of them were quick and simple to print, so I created one myself. - "80mm_fan_grille" is the original design - "80mm_fan_grille_spacer" is a variant with a thinner grille and included spacer to reduce fan noise.
