so im looking into making a 41 qt rack using plywood and painting it to seal it and blah blah like the hundreds that have been made. only i want to make mine so the bins sit sideways due to my Apt being small and i have nowhere where i could put a rack this would stick off the wall 36" sideways it would only stick off the wall ~17" anyways i read somewhere that having the side open like that will cause the 41 qt sterilite bins to warp over time.

this is where i read it below.

i dont understand how or why this would happen and cant find any information on this happening to anyone else. has anyone had this problem or had this type or rack and not had this problem?
