I made a foldable card box for my brother which plays Magic The Gathering. The drawing is done so if you would like to make one, go right ahead! If you are not in to Magic, there is a file without the engrave designs. The Wood I used is MDF 4 mm and I put one layer of varnish to protect it from smelling of charcoal. The dimensions of the inside are 95x69x41 mm. The pieces overlap a little. I put it together with a rubber hammer, so no glue needed.
