Anyone have small piece of black egg crate?

[pws]

Anyone have small piece of black egg crate for sale? I just need a small piece of it to make a overflow snail guard. Was gonna put egg crate with some plastic gutter guard over my overflow to help with snails or fish jumping. I have to measure but it wouldn't be no more than 8" by 8".

Looking to do the same with an overflow I'm building. Following along.
