With a straight-edge and some luck; I made this modification to the default tray in order to house the Plano 3610.The Plano 3610 will store 2 Core Sets comfortably, I recommend keeping the black Quickcast Counters separate to increase [Setup Speed/Ease].
I now have 2 Core Sets + Spell Tome in 1 Core Box. Granted, full spell books might push the lid up a little.
