+- Front-panel screen, LED, rocker, cable-relief, and lower-slot openings are actual through-cuts through the full lid and locating lip so the back side of the printed lid is not skinned over.
 - Body includes screw bosses, recessed lid pocket, lid locating geometry, bottom cable exit/strain-relief notch, and two rear horizontal external belt-loop strap channels to resist rotation on a stand.
