18650 UPS Case

thingiverse

I installed a slot at the top that enables users to insert a thin piece of plastic between the cell + and the battery holder, effectively disconnecting the cell when the UPS is not in use. The switch located on the side of the case solely controls the output power to the USB output port. Consequently, the cell remains connected at all times while it's plugged into the holder. I also added slots to access the 3.3V and 5V connections situated along the edges of the PCB. This modification facilitates easier interaction with these crucial components. Special thanks go out to EunChan Park for making the source files readily available.
