OpenAPS bonnet casing

I gladly accept tips! :D :D If you can donate for a beer or two to make future work better and faster.

This is a V2 of a case made for OpenAPS hardware, Raspberry Pi Zero with Adafruit (Radiofruit) Bonnet 4072 item number.

Adafruit RFM69HCW Transceiver Radio Bonnet - 868 or 915 MHz - RadioFruit

This version has changed snap hooks to grip better. I've tested on two models of the board, should be fine with tolerances and openings for USB and HDMI.

On the back side is a honeycomb grid for better cooling of a Pi.

Let me know what you think :)
