Case for duel USB power supply

I needed a case for a Banggood USB power supply so here it is. The USB is the Dual USB 9V/12V/24V/36V to 5V Converter DC-DC 3A Step Down Power Module that sells for $3 (1073671). This allows my off grid garage to now have a USB power supply. The USB unit just slides into the back and the back holder just holds it in place. See jtandhz on YouTube for further info.
