deck box with nesting lid

A simple deck box with two features.

1. The base can nest inside the upturned lid.
2. A circular tab/hole on each side holds the lid closed.

I made this for transporting a couple of scenario decks when we play Arkham Horror LCG at a friend's house.  The inner dimensions are 72mm x 81mm x 100mm (total); base is 75mm deep, top is 50mm deep, and the overlap is 25mm.  Easily fits cards sleeved with Mayday 7077 sleeves.  The dividers shown in the pictures are 69mm x 98mm.

Tolerance between the base and lid is 0.2mm for the upper portion (closing) and 0.3mm for the lower portion (nesting open).  The model in the pictures is printed with fuzzy skin (point distance 0.4mm, skin thickness 0.2mm) on the lower portion of the base and outside of the lid.

Freecad file included for easy editing.
