Ender 3 S1 Extruder Ultimate Cooling

prusaprinters

<p>The main idea is from this design: <a href="https://www.thingiverse.com/thing:5277750">https://www.thingiverse.com/thing:5277750</a></p><p>I cound not get the CAD files so i designed from scratch in Fusion360 and made use od a partially scan of the extruder mounted on the axis.</p><p>It is devided into two parts, the mount for the part cooling fan and the mount for the hotend fan. For the part cooling I use 5015 turbine, 24V driven up to 50%. For the hotend 404020, 24V driven on 60%.</p><p>I will add a seperate mount part so one can only use part cooler.</p><p>&nbsp;</p><p>For the part cooler You need the trihorn from here: <a href="https://www.thingiverse.com/thing:5398053">https://www.thingiverse.com/thing:5398053</a></p><p>Also some M3 screws and nuts needed.</p><p>Print from ABS or PETG, flat with supports, 13% infill, 4 walls.</p><p>&nbsp;</p><p>I recommend to relocate the crtouch probe to be in line with the axis with this part:</p><p><a href="https://www.thingiverse.com/thing:5568032">https://www.thingiverse.com/thing:5568032</a></p><p>&nbsp;</p><p>&nbsp;</p>
