I wanted to add WI-FI to my Neptune 4 Pro and didn't want to use up my front USB port after discovering there was more USB ports on the motherboard. I just had to add some cabling and activate the ports in Klipper.
I created this cover to route the USB port to the rear of the 3D Printer. It fits snug and I had to gently tap it in. I had to shave off a lot of the rubber from the USB extension cable for it to fit inside of the 4040 excursion, but I never exposed anything that was covered.
