Jeff Ive seen that video, it’s great! Folks should watch it. Frankly between that video, the one from Tom Sandaliver? On how in most cases just use more of a less expensive fillament, the Nathan’s video on the carbon fibers getting in your hands… I would just avoid Carbon Fiber PLA. I had to use a PC Carbon Fiber for an upgrade I did on my XL since thats the fillamet PRUSA specified - but as the folks say, it makes your hands itchy.
