I have an Inky Impression 7.3" display from Pimoroni. The original Inky Impression case I based this on was for a smaller form factor display. I really liked the look of the white case and stand so I've updated the stand to allow my display to rest on it for easy viewing. If I have the time I may eventually remix the entire case, but this is what I have for now.

The current case I've used is https://www.printables.com/model/725292-pimoroni-inky-impression-73-display-frame, but it has no stand.
