Modified Version or Create 2 Bin. The original design does not allow space to connect the power usb to the RaspberryPi 2. I simply moved the mountings to the center a bit and also back to allow more room for USB plugs to not protrude so far from the back. I also have created a cover to allow for a sort of holder so the battery pack that powers the RaspberryPi can be set in the area where the brushes would normally be. The cover helps hold the battery in place.
