This is a deck box for Magic: The Gathering cards. This box will happily fit a 60 card single sleeved deck, with sideboard and a couple of tokens. If your printer allows your to apply differential scaling in the x, y, and z directions, you can print the box bigger in one dimension to allow for larger deck sizes without having to modify the model.
There have been some comments that this is not loading with the correct dimensions into some peoples printers. The external dimension should be.
box: 78 x 58 x 97mm
lid: 78 x 58 x 48mm
