Simple box for 70x70mm cards

I have designed a card deck in printerstudio (custom 70mm x 70mm, 72 cards, 310gr linen). Then I have build this box for storing the deck.

With my printer the two parts fits well with this size. If yours not, you should change size of one of the parts, may be bid at 99%, or 101%)

External size of the box is 80x80x30mm, cards size 70x70x23mm

Note: After using the deck some time... box seems to be small (when the cards are used they get taller... then in some weeks I will make this box 5
