The case

The next part of the process is to design and build the case.

The case is composed of 4 plates :

1. the « base » plate where switches will be mounted,
2. the « supporting » plate,
3. the « spacer » plate,
4. the bottom plate.

|   \_______/    | 5mm « supporting » plate

|     |   |      | 5mm « spacer » plate
+----------------+
|                |
|                | 5mm « bottom » plate
+----------------+ 

The goal is to design 4 SVG files that will feed a laser cutter.

Since I’m not familiar at all with that process, I'm thinking to first design a 3 keys keyboard (volume up, down and mute).

That will limit the costs if things goes wrong.
