140 mm fan dust filter

thingiverse

I needed dustcovers for a noctua 140mm fan for the Lack enclosure for my ender 3 v2, so i made them the easy way. It has the standard hole size and spacing as per 140mm fan standard. The filter itself is made by infil, so set top and bottom thickness to zero. I have added a .3mf from cura with infil blockers with 100% infil to make the corners more sturdy (the top of the two filtes).
