Stepper Cooler Duct Extension
prusaprinters
<p>I noticed that the airflow was very minimal using the original design despite my 24v 4020 sunon fan. This extension seems to increase the airflow across the stepper drivers by a good bit.</p> <p>The version I uploaded here is shorter than the one in the photos. I probably went a bit overboard for my first iteration.</p> <p>Be sure to enable Thin Walls for the airflow rectifier fins. They're .48mm width.</p> <p>The duct is glued in place.</p> Category: 3D Printer Parts
