This thin wall design was created to hold sleeved cards vertically in the Hobby Lobby Art Case. It was also designed to allow for store bought dividers, my own Hero Boxes, and to fit on small printers like the Prusa Mini. The bits (white) box holds loose bits and dials from the core set. You will need 15 of the regular boxes & 2 of the bits boxes.

Here is a link to the Hero Boxes as seen in the pics above:

Here is my old horizontal insert for the same box. I have since abandoned that design since the content outgrew the horizontal space limitation. This thing also has links to the box itself.
