The STLs includes: Case Top, Case Bottom and Buttons. Make sure to print 3 of the buttons.
Also, you will want to add supports to the top of the VGA cutout and the USB port beside the SD card cutout. Please see photos for details.
To assemble you will need 4 x m3 20mm screws and 4 x m3 10mm screws. And some rubber feet for the bottom.
