I picked up a UCTRONICS touchscreen for my Raspberry Pi 3 Model B+ running octoprint for my 3D printer. This screen has a power button on it for the backlight and hence does not fit in any of the available cases on Thingiverse. So I designed my own case and at the same time designed it so it just clicks on the V-Slot rails of the frame of the CR-10. Should work with any V-Slotted 3D printer(Ender). I added cable management to the case so your can route the cables behind the PI and down if required. I also added the power button on the bottom so you can turn of the screen if you like.

For those interested the screen is available on Amazon here:
