This is a remix of the LCD monitor case for the 7in Waveshare touchscreen which I adapted to the 7 inch Landzo touchscreen which I use on my HyperCube build https://www.thingiverse.com/make:332719
The changes include narrowing the case by 6mm and adjusting the hole positions to be correct for the Landzo. I also added mounting points on the back of the case which support the case for the Raspberry Pi https://www.thingiverse.com/thing:922740
I also created a bracket which mounts to the 2020 railing and supports the case quite easily, Two of the brackets will need to be printed.
When attaching the Pi case to the LCD case I used 3mm nylon standoffs but any spacer will work and an M3 screw will thread into the mounting points on the back of the case. I created the back such that it is solid but can easily be drilled out to allow an M3 screw to attach to the case.
SPECIAL NOTE: The LCD board does fit in the reduced space provide but it is necessary to work on it like a puzzle to get it into place. All the screws also fit but a thin screwdriver will be needed for 1 or 2 of the screws on the side with the connectors holding the LCD board in place.
I printed the brackets at 50% infill. The case dimensions are thin enough that with 3 layers no infill is generated.
