The file 'Arduino Uno Case Plus Battery And Buck/boost 3D Printer Model' is (stl) file type, size is 10.3KB.
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
Here is where to get the rocker switch: https://tinyurl.com/yxmmk8pn

Update with a picture showing wiring to power Uno through switch. Data does not connect from USB micro to the power supply, otherwise, I would have wired data across too.
