Aperture Fan Grill

Its a fine gridded fan-grill for radial fans, like they are used on the Prusa i3 / Prusa i3 MK2 / Prusa i3 MK2S / Anet A8.
For installation it may be necessary to use longer screws, which are supplied with the Prusa i3 printers, in their spare-parts bag. On printers, where the outtake of the fan faces downwards to the buildplate, the longer mounting bracket, needs to be fastened at the upper left screw. I reccomend to print the newer version, which is more quiet beacause of its larger holes.
