Update 05/09/2023:

I essentially re organized my office and created two additional options for this mount. One of my printers was better to wall mount this screen and the other I wanted to attach it to the base with a slight angle, similar to how it was mounted to the side. I also wanted to be able to mount all of the 2.5 mm screws to the screen before affixing the mount to its final location for ease of installation. Instead of using t nuts you can now mount it in place of the plastic cap for the rail. Should work on the Vyper or Kobra Max and likely other printers. Make sure to reorient the prints so they need minimal supports. The Vyper mount prints well if you only use supports on the square floating attach point. Might print decent without them as well.

I designed this case in FreeCad for the Ingcool 7in touch screen. This touch screen has much better viewing angles than most I found on amazon. Like another design I made, I created this using the 3d file of the touch screen the manufacture provided here: http://www.ingcool.com/wiki/7DP-CAPLCD

The fit isn't perfect but it came out good enough for my use. Be sure to flip it on its back when you go to slice it before printing. I think the screw holes to secure the screen to the case might be slightly off which seems to have caused the small gap on the left (can see it in the actual picture). I have included some holes on the bottom and bottom right so you can attach it to the rail of the printer. I used tnuts to secure it (need to do this before mounting the screen). It was kind of a pain to get the screen mounted while the case was already fixed to the printer but I wasn't sure how else to accomplish this. Holes on the back were placed to reduce filament usage and allow the screen to breathe some.

One final thing, this screen comes with a small standoff built in, but the screw size is not really standard. Its M2.5
