18650 UPS Case

I added a slot in the top to be able to insert a thin piece of plastic between the cell + and the battery holder to disconnect the cell when the UPS is not in use. The switch on the side of the case only turns on/off the output power to the USB output port. The cell is connected at all times when it is plugged into the holder.

I also added slots to be able to access the 3.3V and 5V connections on the edges of the PCB.

Thank you to EunChan Park for making the source files available.
