This is a simple organizer for testing keyboard switches. There are a few improvements that I made over the spartan version that my switch supplier provided. The "plate" area of the sockets is 1.5 mm thick, which is the correct size for plate mounting these switches (this prevents damage and deformation to the switch housing).
The plate is also reinforced with a grid of gusseting, and this provides a bit of rigidity.
Note: The blue print shows correct chamfer on the edge.
