Ender3 Board Fan

prusaprinters

<p>Board fan of the ender 3 does not turn on till 2nd layer because its coupled with the filament cooling fan, I do a lot of large prints and don't feel comfortable having the fan off for so long.</p> <p>so I designed a easy fix</p> <p>Needed: 50x50x15 blower fan (WINSINN 50mm Blower Fan 5V 5015) on <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a> they have them with USB so no wiring needed, fan is held in place with hot glue, I guess you can do it prettier than me :-)</p> <p>I attached rubber bumpers to keep it from moving, double sided tape works too, make sure wires are out of the way, <a href="https://www.thingiverse.com/thing:2880021">https://www.thingiverse.com/thing:2880021</a> clips works best.</p> <p>Make sure the fan pulls the air out of the Board case as the build in fan pulls air into the board case.</p> <p>UPDATE:</p> <p>After using the fan for a while I noticed warping on larger Prints only on the right corner, and I guess it might be the fact that the fan blows air right under the Bed and cools the right corner down. I might have to add a duct to divert the air to the side or front.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Resolution:</strong></p> <p>0.28</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>30</p></div> <p><strong>Filament:</strong> Sunlu PLA Blue</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Holes print fine without supports</p></div> </p></p> Category: 3D Printer Accessories
