Ditto on the cardboard cutout. I got a thick aluminum lid from a hardware store. Since my immersion cooler doesn't exit at the precise edge of the lid, I had to cut in about 2 inches x 1.5" wide. I then cut that piece down and JB-welded a hinge on this little piece to close the lid around the outside of the immersion chiller. It's somewhat near being air-tight! It also partially locks the lid in place, so when an earthquake comes the lid won't fall off
