Small mod of CR-10 FANG OEM fan duct assembly

thingiverse

Update 1 Added _04 variant featuring a spot for a M3 nut allowing for precise height adjustment using a M3 screw as demonstrated in video. Consider adding a small spring (depicted in red in the video) if deemed necessary. https://www.youtube.com/watch?v=SRCep2IaOyQ Original post I made a straightforward modification to the fan duct, tailoring it to my needs. I discovered it easier to remove and adjust the fan duct mounting height, which allowed better cooling of the two screws on the CR-10 and heat break if desired. Having a thin layer of cool air around and not being touched by plastic that heats up during printing might also contribute to improved results. This part can be printed in PLA, though I haven't tried it. I printed it in PET-G instead. With this mod, I experienced better cooling, so you may want to try it and see if it suits your needs as well. The source is an excellent part, thanks to the authors.
