Fan Grill

thingiverse

This is a custom fan grill for the 120mm fan that keeps my CR-10 S4 controller box cool within its enclosure. It's engineered to have a 120mm hole cut through 3/4" MDF, and this grill fits snugly inside that opening. The mounting holes for both the fan and the grill are carefully aligned so you can use one bolt and nut at each corner, passing through the MDF to secure everything in place. This particular setup pairs perfectly with a 120mm Cooler Master Sickle Flow 120 Fan.
