Designed for a Magic: The Gathering Commander deck that rolls a lot of dice, the interior card space is 2.75" x 3.25" x 3.75" (~70mm x ~82.5mm x ~95mm), which is half an inch larger than that of the Ultimate Guard Sidewinder 100+ deck box as a point of reference – that leaves room for a double-sleeved Commander deck alongside tokens/an Attraction deck/etc.

A small disclaimer: This was made as a personal project, and while I am very happy with the functionality of the final design, I am relatively new to 3D printing overall. That means a little filing/sanding to get the tolerances right will likely be necessary, and the interior supports can be a bit obnoxious to remove. I very lightly sanded the interior bumps that lock the dice drawer in place first, and then sanded the slots that the slats go into – these should be inserted with the bumps facing down, and slowly dialing the width of those slots in will allow them to be removed easily with a pinch but still stay secure otherwise.
