So I found a solution to one of my problems with the project. Initially I was going to mount the display on my TGY-i10 radio but then I was like goggles are cooler. Off the shelf solutions are pricey so I was gonna design my own and 3D print them. Thanks to openess and sharing I won't have to:

Everything right there to print goggles for the 7 inch screen I have wired up and working with the 5.8GHZ radio. Now just gotta see if it will fit on my Rep1 style 3D printer bed.

Stay tuned.
