Great idea! Only one problem though, you should have brought that to market!
Well what's to market? The egg crate?It's a DIY idea made with egg crate that I've shared with everyone so they can use something that works nice and doesn't cost much at all to make. It's not a product, it's an idea that most people can DIY. Place something similar in a LFS and I bet most people would stick to DO It Themselves.
