Stanley Accessories Case - Modification (MTG)

I modified the Stanley Organizer case (10 compartments) with some 3D-printed parts to be able to hold up to 7 Dragon Shield Gaming Boxes. It also fits a playmat and some kind of life-counter device (my old smartphone).

I cut a bottom plate out of a thin wood board and glued the 3D printed parts on it.
There's a little wiggle room for the boxes to the case lid, but nothing falls out of place when shaking.
