This case works for the this particular display ("7inch HDMI Display-B" [http://www.lcdwiki.com/7inch_HDMI_Display-B], no longer available from [https://a.co/d/fBu1MvT]), other models may have varying mileage. There doesn't seem to be any branding on the display, but it appears similar to [https://a.co/d/gGpYUB4]. May work for the same display labeled "7inch HDMI Display-C."

The design may be a bit bulky, but it prints sturdy and that was my goal. Though it includes holes for M3 screws in the corners to hold the backplate to the faceplate, it printed snug enough that I haven't actually felt the need to install them. (Previous version was actually TOO snug when I learned my printer was under extruding significantly, files have been updated.) Redesigned version has rounder corners, flatter face, more centered stand and mount holes to accommodate a hole in the back to access the on/off switch on the display.

A Raspberry Pi can be mounted to the back (with or without the stand) using M2.5 screws.

Optional mount for Pi camera (shown here with a V2 and V1.3 installed). Can be mirrored if installation on right side is preferred.
