Edison stackable board wearable case

Hi -

I’d like a case that would fit the Edison and breakout stackable board (the base, oled, battery, &etc). Either it could be something that is built in layers like the Raspberry Pi Zebra case - and depending on the number of boards in the stack different numbers of layers could be used - or even better if there was a sealed plastic ‘accordion’. This would keep out moisture would grow to fit the number of boards in the stack.

On one side of the case there should be an attachment for a strap so that the device can be worn.
