Case: two more body screws near the front

The base only screwed to the body at the back. New bosses in the side walls sit just behind the display, clear of the bezel's slide-in path; the base rim gets a gap around them and the feet part now has 6 feet.

 PETG is a good choice: the display warms the inside by a few degrees. PLA
 works if the case stays out of the sun.
