Parametric Playing Card Holder

We play a game called Golf that requires 2 decks to play. We either had to rubber band the decks together or they ended up all over every time the decks got bumped. I created a holder for these and then set parameters so you can adjust it to whatever cards you are using. Cards Against Humanity works great in these holders. The current size will hold standard playing cards (2 decks worth) so you can halve the height for a single deck.
