The box is 7.5 inches by 7 inches and has 2 hooks for USBs) on each side. Its purpose is to hold the USBs in an organized way. The box will hang on the metal cage in the corner of the room. It will hold 3 USBs in the box but there is enough room for more than that. Our results are illustrated in the model. We created the box so USBs could be more accessible.
