<p>Replace noisy hot end fan on the Sprite Extruder with a quiet 5015 blower fan.</p><p>This is a remix of the <a href="https://www.printables.com/model/209504-ender-3-s1-hotend-fan-4020-replacement-bracket">Ender 3 S1 Hotend Fan 4020 Replacement Bracket</a>.</p><p>This remix mounts a 5015 blower fan instead of the 4020 blower and is further offset from the gantry so that it will clear the x-axis enclosure on Ender 3 Pro and other similar printer models. This remix is also designed to snap a 5015 blower fan into the housing without the need of hardware. </p><p>If there is a desire to secure the fan into the bracket, you will need to use 1 or 2 M3x18 screws depending on the bracket you choose. I only had M3x20 screws lying around, so I added a hex nut to mine to shorten the threads. For the 2-screw fan bracket, no hardware is necessary as the fan will snap tightly into the bracket.</p><p>What to Print:</p><ul><li>backplate-sprite</li><li>Choose either 1 screw or 2 screws fan mount:<br> a. fanmount-1screw - smaller profile, less materials<br> b. fanmount-2screws - adds an extra screw mount for a tighter fit</li></ul><p>Hardware:</p><ul><li>1 x 5015 blower fan. I use these types: <a href="https://a.co/d/0GwO1du">https://a.co/d/0GwO1du</a><ul><li>or a 5015s ultra quiet 5v fan <a href="https://a.co/d/dPNmHxV">https://a.co/d/dPNmHxV</a> (I used this one)</li></ul></li><li>1 x JST-GH connector (1.25mm pitch) or splice/solder the old one to the new fan</li><li>2 x M3x18mm screws (optional) to secure the fan to the bracket</li><li>1 buck converter (optional) if you want to use a 12v or 5v blower vs 24v<br> </li></ul><p>Printing Suggestions:</p><ul><li>Support: Not required</li><li>Layer Height: 0.2mm</li><li>Filament Type: PLA or PETG<br> </li></ul><p><a href="https://www.thingiverse.com/thing:5436876">Ender 3 Sprite Extruder hot end fan replacement with 5015 blower by Locomoco - Thingiverse</a></p>
