You looking for something like this, Paul? If so, I have a ton of their stuff and they are a great company to deal with. https://www.fastcap.com/product/kaizen-foam
sheesh... I literally just found this, https://www.amazon.com/Fastcap-Kaizen-Foam-57mm-Black/dp/B007J2JJYK
then came back over here... to your post!

not sure how those will be for snugness.. not sure how "oversized" you could make them, and still get them in and out easy... as opposed to mush foam, which you could definitely compress it good side to side.. i'm gonna cut that white stuff, which i'm thinking is similar to what you posted in it's mushyness
and see how it fits..*Ryoken - trying to ignore the crazys in the cranium trying to get him to do a magnet layer, than a cutout foam layer, than the top foam.... *

i'm thinking bottom layer of black magnet.. than maybe a cutout orange foam to match Mutt somewhat.... than the top cover foam would be black.....
maybe down the road.. i can upgrade from just magnet and foam when i really dial in what i want tool-wise in the rig....
