This is a negative/model of a 2.8" 240x320 LCD so you can make a case, wall plate, whatever and mount the LCD in it. The area around the model needs to be at least 7.5 mm thick or the pegs that go in the PCB holes cant be melted to fix the PCB to the thing you are printing. I typically make a "bed" to put the LCD in for this purpose.

The LCD I am using and have made this for is this one:

Make sure the thing you are putting this into is at least 7.5mm thick - at least immediately around the LCD.
