Replacement Foam for console boxes

Hi all i,am looking for a way to complete some of my console,s that i have boxed i have an nes control deck and an nes action set that miss the foam in the box so i was hoping i could find some online. but i found nothing online about replacing this foam. i can find foam inserts for my games but i,am looking for the bog foam parts for my consoles instead maybe some of you know how/where i can get some?

 

I was going to suggest getting a giant block of foam from an art supply store, but it looks like this place custom cuts the stuff.
