Print both display parts top and bottom and two (2 !) distance pieces. I then removed the yellow FBAS cable which I didnt need and unsoldered the barrel connector, fiddled it through the whole and resoldered it. The two distance pieces hold the electronics controller board in place. A layer of thick cardboard separated the aluminum back of the display from the electrical contacts of the controller.Everything fits without any tools and without any glue. But to be on the safe side I glued the two halves finally together. Because I intended to use this display outside in the sun (as display for my drone) I constructed a visor to keep the sun outside.
