USB Power Cutter
thingiverse
I designed this solution to easily disable my printer's power supply when I flip the switch on the power button, thus preventing any potential damage caused by powering it through the USB port. It simply consists of a protective casing that houses a pre-soldered male/female USB-A connector - just be sure not to solder the power pin in place.
