Light Switch Enclosure
The design goal was to make an enclosure for the PCB that would fit in a standard in-wall electrical box. It was originally envisioned as a 2 piece enclosure with the PCB in between the 2 pieces. But it evolved to a 3 piece design because my 3D printer could not easily print the side that would face the room, and then one would not have access to the Mode and Reset buttons of the Particle Photon. The plus of the below 3-piece design is that the proximity sensor board fits in the Decora rectangle, and easily connects to the switch PCB via headers. And the middle enclosure piece provides access to the Mode and Reset buttons while shielding most of the rest of the PCB (so you would have to really try, or be very careless to touch the parts of the PCB with high voltage). Unfortunately, little Johnny or Debbie could pry the front rectangle off so it is not an optimal design (if you glue it together, you no longer can access the Mode and Reset buttons of the Photon) . But this is what I went with. (Have pondered making it a 2-piece and printing it at Shapeways whose 3D printers can handle the job and risking the occasional need to disassemble but even then, access to the Mode and Reset buttons would be needed). Note that I am by no means an Autodesk Inventor expert so the designs and methodology of design may have amateurish aspects.
