Gigamons / Gigamon card holder and the needed 3 stones in 3D.

Print the holder to keep the cards neatly stored in the box. The height of the card holder is such that the cards cannot fall out once the game box is closed.

The holder has “Gigamon" engraved.

See the game on boardgamegeek here.

Alternative design

There is a card holder without the stones on the sides available, too.

Customization

You can use the holder and customize it to your liking using the free tool OpenSCAD.
