fan size reduction grill

You can decrease the fan diameter from 92 millimeters to 40 millimeters when a larger fan is not necessary. If you require a grille for your fan but lack a suitable size, this grille will accommodate 92, 80, 60, and 40 mm fans perfectly. I am currently refining the design.
