Ender 3 V2 40x20 Hot End Fan Shroud
thingiverse
I wanted to switch out the stock hot end fan with a noctua A4x20 but couldn't find a new shroud that I liked. I love the stock shroud, so I basically just redesigned it to fit the larger fan and removed the grills to help with noise. The noctua is a 12v fan so you will need a buck converter to drop the 24v from the psu. P.s. I did this in conjunction with upgrading the mainboard and psu fans to noctuas as well (https://www.thingiverse.com/make:903901) Fan: https://www.amazon.com/Noctua-NF-A4x20-PWM-Premium-Quality-Quiet/dp/B071W93333 Buck Converter: https://www.amazon.com/gp/product/B08Q2YKJ6Q/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1
