Ender 3 Sprite Extruder hot end fan replacement with 5015 blower

thingiverse

Replace noisy hot end fan on the Sprite Extruder with a quiet 5015 blower fan. 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> 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. 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 to use. I only had M3x20 screws laying 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. What to Print: 1 backplate-sprite 2 Choose either 1 screw or 2 screws fan mount: a. fanmount-1screw - smaller profile, less materials b. fanmount-2screws - adds an extra screw mount for a tighter fit Hardware: 1 x 5015 blower fan. I use these types: https://a.co/d/0GwO1du or a 5015s ultra quiet 5v fan https://a.co/d/dPNmHxV (I used this one) 1 x JST-GH connector (1.25mm pitch) or splice/solder the old one to the new fan 2 x M3x18mm screws (optional) to secure the fan to the bracket 1 buck converter (optional) if you want to use a 12v or 5v blower vs 24v Printing Suggestions: <ul> <li>Support: Not required</li> <li>Layer Height: 0.2mm</li> <li>Filament Type: PLA or PETG</li> </ul> <a href="https://www.printables.com/model/244570-ender-3-sprite-extruder-hot-end-fan-replacement-wi">Link on printables.com</a>
