2x140mm (280mm) fan dust filter grill

It was originally made for Corsair Carbide Air 540 top, but should be usable on any 2x140mm (280mm) fan holes. Print two of them and use the lip to adjust the gap if there is any.

Use filters that look like that (search Ebay for “140mm dust filter mesh”):

Mount everything with rubber “screws” (search Ebay for “fan rubber mount”):

Print with PLA or PETG if the surroundings will be hotter than 50-60°C.
