Just a silly spacer for the Joking Hazard big box. I was tired of cards falling over flat and being hard to scoop up. This spacer prevents that from happening as long as that channel is mostly full (around 300 cards).
You can print one or two, or how many you want. Could probably be easily modified for other card game boxes.
