Doom-styled SVG files that inspired the build are included. I added them as modifiers for MMU printing.
Recommended settings for single-extruder MMU are here on this remix of the Parametric Rugged Box:

The lid can be printed with standard settings.
The box will need a brim to prevent the corners from lifting. I had no issues with 8mm brim, but that will depend on bed adhesion and filament types.
The author remixed this model.
Re-modeled from the Rugged Box model to have a single latch.
The latch and card separators are unchanged.
