Heat Pedal to the Metal Gear Shift Box

I use an Ender 3 S1 pro single filment printer and wanted to use the excellent gear shift box by LDub. I have remixed the box by LDub so that it prints the colors desired utilizing differential heights and the change filament command. When using Cura to slice using 0.2 layer heights and a 0.4mm nozzle I add filament change commands (via menu choice Extensions → Post processing → Modify g-code) at layer 31 from white to black, layer 34 to red, 37 to orange, 40 to blue, and 43 back to white. This remix required a re-do of most of the top so you will note different font, different flame, different thermometer, etc.

See images and see what you think. I have included the box bottom unchanged from LDub for convenience. I recommend printing one of the bottom in each of the player colors.

Feedback welcome!
