Review on 💪 Sturdy and Sleek: Black Nominal ABS Sheet for Reliable Thickness by Cody Cobbs

We used these to cover the cut outs where our fish tank hangs from the filters we installed earlier. We switched from built-in filters to aquarium gravel filtration and there were large rectangular holes in the 4 aquarium lids that let light through (light pollution). Large holes were unsightly, a possible spot for adventurous fish to jump out of the tank, and the hole could increase evaporation from the tank. We've searched online and found people suggesting using a toaster set at 250 degrees Fahrenheit to heat a plastic wrap (already cut to size) on a foil-lined baking sheet until it's very pliable. The plastic was as pliable as uncooked lasagna noodles. Using a spatula and oven mitts, we placed a sheet of hot plastic on the opposite top front corner of the gas cap to use as a mold. It was hot work, the part cooled in its new shape and solidified again.
