This is a remix of:
https://www.printables.com/model/413639-removable-btt-hdmi7-screen-case
I designed this remix for the HDMI V1.2 where the cables are in the center of the back (see picture). It has a low profile bezel so it doesn't cover any of the screen. Protruding buttons on the outside for easy access to rotation and brightness. It also allows for horizontal as well as vertical mounting.
