Much wider slots cut out for cords - 20mm each, centered on original cutouts. My cat's heating pad has a 20mm Ø cord as it has extra wrapping for bite resistance. I still needed it to be much taller, but just this modification might be useful to someone. I found the original cord slots far too thin to fit most power cords.
Please ignore the bad quality of my print.
