CR-10 Large Nozzle Extended Stock Style Part Cooler Fan Duct

thingiverse

I prefer the streamlined setup of the stock CR-10, but when I upgraded with a larger 0.5mm stainless steel nozzle to print abrasives, it was substantially wider and longer than the standard nozzle. Consequently, all part cooling fan ducts would obstruct the middle of the nozzle instead of targeting its tip where airflow was most critical. This straightforward modification extends the original design while also adjusting the slope of the wedge inside to optimize air flow across the tip more effectively. I have utilized this upgraded model on my machine for the past three months and it has performed flawlessly, eliminating the need for supports during printing.
