When you want to search for something like this, never search for “art storage” “organizers” etc. They tend to be shite.

Start Here and work your way down the rabbit hole. The one i linked is a start, it’s a good organizer that isn’t meant for it specifically but you just gotta get creative and re-purpose it. Keep looking in that category and i’m sure you’ll find one that suits your needs. Good luck

Edit: Even found a YT video for it so you get the gist of it.
