Ender-3 Vent Ring with Windshield

thingiverse

I think that my extruder has unoptimized parasite airflow caused by the always-on frontal fan cooler. Turbulences from this airflow are partly directed downwards onto the printed object, potentially leading to undesired thermal effects. This issue is particularly significant when printing with ABS, as it's extremely sensitive to unwanted air flow. The printed wind shield should be made from a heat-resistant plastic like ABS or another suitable material. PLA isn't a good choice because it will melt and soften during usage in high-temperature environments. Thanks go to Filboyt, the creator of the original vent ring idea for the Ender-3. This concept is truly innovative!
