card-o-matic vXerra

The original version has a gap where the cards can slide out if you carry it in your backpack or wherever (see picture).
To prevent that, in this remix I have lengthened those parts so that they are inserted in a little space. By sheer serendipity, they stay wedged in and don't accidentally open.
I have taken the exploding kittens cards around with that box and it works great.
