I have grown tired of vertical boxes to hold my Warhammer Datacards so decided to make myself some horizontal ones. I wanted a lid that slides into place from the side so the box can be tipped upside down without the cards spilling out. It needed to hold at least 60 cards using the Standard Size card sleeves (91mm x 66mm). These are the results of that effort!

Quick Stats
- Standard Card Sleeves, 91mm x 66mm
- Holds roughly 60 cards in sleeves
- Lid slides on from front of box, locking into place

I changed the blank lid to have various Warhammer 40K factions' logos on them and printed them myself. Sadly, due to copyright, I cannot share those designs here. Instead, I have included the 3MF file for the pieces (along with STLs, obviously) so that you can make your own lids!
