Holleytech energy meter IR mount

I designed this to mount an IR diode to my energy meter (Holleytech DTZ541). This thing only houses the IR diode and the wiring. All other equipment you need is placed externally.
In my case I plan more wiring to my gas meter so I can connect just one ESP8266 to the IR diode (energy meter) and the reed sensor (gas meter).

To hide the wiring you simply slide the lid from the top into the body. In my case it fits quite nice and don't need to be glued or else. I'll update when I've finished wiring.
