It's 3 pieces (back mount), front cover plate, and a roof for the usb (so it won't get rained on but is still accessible). You will need to hot glue the usb cover on. I also left a recess behind the display window. You can cut out a thin piece of PETG, or if you have some scrap clamshell material lying around use that (this will also need to be hot glued in from the back).

I'm using #4 x 1/2" self tapping screws for all the holes:
