A deck box made for Magic the Gathering cards that can hold a commander deck (100 cards) in addition commander card (fits in the small slot next to the main compartment). It also has a dice tray/compartment under the place where the deck is stored. Though I am pretty confident I got my measurements right, I have not printed and tested this yet, so I encourage you to print it if you want to tinker with it, but I am not guaranteeing that it will work 100%.
