<p>Update: Ahmad has created a version 2 of his design - please go check it out and donate to him: <a href="https://grabcad.com/library/mbot3d-mk2_rev2-0-ender7-style-fan-duct-1">https://grabcad.com/library/mbot3d-mk2_rev2-0-ender7-style-fan-duct-1</a></p> <p>Important: This is a remix of <a href="https://grabcad.com/library/mbot3d-extruder-mk-2-mod-1">https://grabcad.com/library/mbot3d-extruder-mk-2-mod-1</a> by Ahmad Sunardi</p> <p>I think this is the most beautiful fan duct for the Ender 3 V2 increasing the cooling performance by using two 4010 blower fans. However the original design of the above creator had some issues which I fixed in this remix. Mainly the hole on the front for the heat break cooler - it is simply too small so that the heat break was not cooled sufficiently. Also I added a tab to reduce air leaking onto the part.</p> <p>The design consists of three parts:</p> <ul> <li>Frontplate_V3.stl - the main body</li> <li>Backplate_V3.stl - used to mount the main body to the carriage</li> <li>Airducts_V3.stl - holds the two fans</li> </ul> <p>Alternative for a 4020 Sunon fan:</p> <ul> <li>Frontplate_Sunon4020.stl - the main body</li> <li>Airducts_Sunon4020.stl - the airducts</li> </ul> <p>This air duct has some neat features:</p> <ul> <li>dual 4010 fans with part cooling from both sides</li> <li>the main body is hinged and can be removed with only two screws</li> <li>the blower fans sit in a seperate housing</li> <li>BL Touch works with the stock metal bracket</li> </ul> <p>I would not recommend to print this in PLA as it sits quite close to the hotend. I used PETG and GreenTec - both work perfectly fine.</p> <p>Update: I have added a version for a 4020 Sunon fan as the heatsink fan. The respective files are named*_Sunon4020.stl.</p> <p>Update 2: If you need help assembling the shroud: mattpker has create an assembly video right here: <a href="https://www.youtube.com/watch?v=Ayqa3cT2KjY">https://www.youtube.com/watch?v=Ayqa3cT2KjY</a></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 Pro</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.12mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div> <p><strong>Filament:</strong> purefil GreenTec Pro Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>The main body (Frontplate_V3.stl) and the backplate (Backplate_V3.stl) can be printed without supports but the air ducts (Airducts_V3.stl) need supports from print plate.</p></div> </p></p></p> Category: 3D Printer Parts
