My family plays a lot of 3-13 which requires playing with many decks of cards. This becomes annoying with a card shorter tray since you constantly need to refill, or they all fall over. So after trying a few existing models that didn't work out, I decided to make my own.

This is a standard deck tray, commonly used for Canasta, but it's a bit taller. Feel free to scale it up even taller for your prints.

Update! Added a 3-gang holder, just by overlapping two 2-gang holders and shifting one by 83mm.
