A basic cover + case design for a 7inch touchscreen from FreeNove with a Raspberry Pi 4. Requires 4 long screws at each corner to secure the cover to the case. I made some holes in the case so that you can pass some cables through it to connect the power and USB.
You will notice the columns inside of the case (not the cover), they support the touchscreen which is connected to the Pi which keeps the Pi off the bottom. Since it's a touchscreen, the pressure on the screen is where the support is needed. After securing the cover to the case, it will secure both the touchscreen and Pi in place so that it doesn't move.
The author marked this model as their own original creation.
