Here are some pictures of the wood frame I made for the RPi display. I bought a display as soon as they were available then set to work creating something to hold it. Unfortunately by the time I got it finished the firmware had changed and the image rotated 180. AARGH! I can't rotate the display in the frame because I offset the RPi so the ports are available at the side rather than in the back. But I thought I'd post pictures to provide some ideas for anyone else doing something similar.
After looking at it I decided that rather than stacking the two circuit boards it would work better to extend the RPi over to the side. That placed the ethernet and USB ports on the right edge so they are easier to connect, and makes it similar to a notebook or tablet setup (in the next version they will be on the left side, everything rotates 180deg). I also put a power plug on the end with the ports.
It will lay flat, stand it up vertically, or lean back.
I slotted the holes in the frame where it fastens to the display backplate, so I'd have a little bit of slack up and down to shift it, I didn't want any pressure on the flex cable coming out of the display. But I didn't have any washers that would cover the slots like I wanted, so the two thin wood strips are actually just "washers" to cover up the slotted holes underneath. I cut two plastic spacers to support the end of the RPi where the ports are, and screwed those to the frame, and I also cut down the provided standoffs to lower it a little.
After studying the situation a bit I think I can rework it to rotate the screen, so all may not be lost. I can use a flush cut saw and cut off the two side pieces, then rotate the leg assembly 180deg and make two new side pieces. I also need to make the frame itself a little wider so the ports come out flush with the sides. I made the frame first, then decided to offset the RPi so the ports were on the side, but my frame was a bit narrow for that, so the ports extend out past the face some. I'll fix that in the rework. I think having the ports available on the side works much better than having them around in back.
