Arduino Uno case plus battery and buck/boost

This is an open top Arduino Uno case with a buck/boost converter+18650 battery compartment.

There is a rectangular hole for a rocker switch.

I plan to run usb mini from the buck/boost converter (the four USB lands in this image) over to the Arduino via on/off switch.

Here is where to get the buck/boost module: https://tinyurl.com/y362g4st
