I designed this backlight panel to replace the original panel and provide more light for the interior. Black and light blue ABS was used and printed at half the normal speed in order to make a smooth panel. Some cleaning and filing is required to make the parts fit well. Before trying to snap the LED panel into the back panel make sure it will fit the opening from the front side. Simplify 3D slicer was used with supports and 50% fill. Two banks of 5 LEDs each in series with a 390 ohm 1/4 watt resistor and driven via the existing 24V supply provides extra internal light. I also added connector between the panel and power supply and an On-Off switch to the front panel.
