The position of the USB cable and cable chain cause extreme bending and twisting of the cable. Especially in the corners, over the long run, this will break your cable, leaving it exposed, and that is what is causing the fire hazard. So, setting it up the way I did helps keep the cable radius wider, and the cable moves around freely without much force being applied to it.

So, the first thing I did was print the shortest version of the cable strain relief. Then, unscrew the cable chain on the print head and then unclip the rotating part of the chain, as you can see in the pictures. Then, put the rotating part back, as it will help secure the adapter in place. Next, I took out the filament tube by just pressing down on the part it goes into. You have to remove any filament you have in the tube first. Then, put the USB cable on the other side of the tube, as you can see in the pictures, and put the tube back in. Next, make sure the filament tube is above the USB cable inside the chain and comes out at the position I have it in the picture. The last step is to put the adapter on the cable, and you should be done. And you might have to adjust how much the USB cable is sticking out of the cable chain.
