Because of all the various card games we had with a side by side box similar to the original Uno boxes, I wanted something similar so that it fit in the storage space better than the latch close card boxes like https://www.printables.com/model/594687-uno-flip-card-box.  Also wanted something that would hold the original instructions just in case we forgot.  

Nothing against the latch close boxes, printed one and it works awesome.  Just wanted to see if something different would work.

This box is designed to fit a deck of Uno cards, or similar, half on each side, with the original instructions setting on top.  It uses magnets (8, round 8mm diameter x 2mm thick) to hold it closed.  4 magnets on the bottom and 4 on the top.  Includes stl files with the logos for printing with alternate color, as well as a blank lid for whatever logo you may want to add, or just let it be blank.
