Appa & Momo

Characters from Avatar The Last Airbenderhave 2 negative cubes sized for usb-c plugs like these from amazonon/off switch like these from amazonYou can resize or remove these for your preferred plug or on/offI have also started using the low profile cob lighting for boxes and have been extremely happy. These are the 5v cob led strips I use. couple drops of super glue along the edges will seal it up permanent or you can use hot glue and should be able to open if you ever need to.
