Ender 2 Pro 4010 Blower Fan Ducts

prusaprinters

<p>I pieced together a hotend for my Ender 2 Pro and the stock part fan duct would no longer work for my needs. I designed these ducts to replace the stock ducts. YMMV on if it'll fit your printer or not. There is a tall and short version. The short version is 2mm shorter than the tall version. On my modified Ender 2 Pro hotend, I use the long version.&nbsp;<br>&nbsp;</p><p>If you have dual fans, a left fan version is supplied. I used a <a href="https://www.printables.com/model/321587-ender-2-pro-dual-parts-cooling-fan-mount-ezabl-min">mount</a> that <a href="https://www.printables.com/social/233133-the-300lb-gorilla/about">The 300lb Gorilla</a> designed for me to mount the fan along with the EZABL micro. To mount the fan on the left side, I drilled 1.5mm holes for the top holes and used M2 bolts. The duct mounted with 2 bolts with nuts on the bottom.</p><p>The right duct mounts with the stock M2 bolts threaded into the stock mounting plate.&nbsp;</p><p>Print settings:</p><ul><li>Layer height: 0.2mm</li><li>Infill: 20%</li><li>Material: ABS</li><li>Supports: &nbsp;From build plate only. You mainly just need supports under the screw mounting points.</li><li>Orientation: Print with the duct on its back against the build plate</li></ul>
