Step 4.

Place the fan into the five gallon bucket, front side up. If you bought the Holmes brand fan pictures here it will fit VERY snugly. You don't even have to secure it in place.

(If it is smaller than the opening, then cut a hole, smaller than the diameter of the fan, into the bucket lid. Use some floral wire and secure the fan to the lid so that you can place the lid onto the bucket.)
