Hey CHRISTIAN---I had a thought for a box that would show alot of plugs by making it long,narrrow, and shallow.
maybe 4in wide by 3in deep,and as long as you want.If you cut out the sides like a gun rack you can lay the plugs horizontal and still be able to take them off to look at them.
I would say u could hold 6 plugs for every foot so u cold get 30 or so plugs in a 3 ft box.
Just a thought ,hope it's helpful.
