Added hooks to mount the front and back plates on the case body. Resized a little bit the top opening on the front plate to be same thickness as the case body.

EDIT Added Front plate with grill option as well. EDIT2 Added LIP part and option on Front plate with hook mounts for the LIP part. It should fit snug, if not you can melt a small piece of filament to join the two pieces without glue (see photos).

I would add mounts for the screen, but some double side tape or hot glue is good enough for it just sitting on the table. And I wouldn't want to add mounts for only one type of screen anyway.

For the photos I used an 3.2inch ILI9481 TFT I had laying around but it does not have touch and its 480x320 so it does not extent to the whole screen. It plugs directly on the Mega2560 with no between adapter board. Eventually I'll resize the code graphics to fill the whole 480x320 screen too.
