A simple box with 3D printed sides, and laser cut top and bottom.

The STL file is for 3D printing.
The DXF file is the vector file for Laser cutting - you can delete the text in the center if you just want blank wood end plates.

This was for some switches and a DC-DC converter in a very small off grid solar system for a friends van.
