Summary

This is a quick design to hold the cards in place in the Witchcraft! board game box. The holder should fit in the original card board insert.
Just make sure of the dimensions of your game box since some of the newer print runs have a smaller box than the 1st print.

The insert is designed to fit sleeved cards.
The sleeves I'm using in the picture are the usual "penny sleeves". The fit is pretty tight even with those, so if you're using thicker sleeves, I recommend you scale the model in X and Y-axis to allow for 0,5mm extra room.
The smaller slot in the bottom is for the 45x64mm cards.
