The CYD easily lifts off for access to ports and buttons on the back. The stand is mostly hollow. I printed at 15% infill but a higher infill wouldn't use a much filament. No supports needed and no screws or other fixings.
My CYD is the CYD2USB variant with micro USB and USB C sockets, but as far as I know both versions have identical dimensions.
