Dual Part Cooling Fan Mount / Shroud for Prusa i3 MK3S (Reinforced) (Extended)

prusaprinters

<p>This is a remix of the <a href="https://www.thingiverse.com/thing:3869092">dual-fan nozzle cooler for Original</a> Prusa i3 mk3S by ANTALIFE (which is itself a remix of <a href="https://www.thingiverse.com/thing:3697665">the original by RosyRL</a>) .</p> <p>I've used the original for a while. While looking to replace it I discovered ANTALIFE's "reinforced" remix and I really liked the concept.</p> <p>However, I also just switched to a different heat break (a Slice Engineering Copperhead). It is slightly longer than the original Prusa E3D heat break, so at the default size my previous nozzle cooler points at the heater block rather than below it, causing some problems and not doing its job very well.</p> <p>This is a remix that is 2mm "taller" -- that is, the fan outlets are positioned 2mm further below the extruder body than the original. This makes it so it is positioned in about the same place (relative to the nozzle) as the original with the OEM heat break.</p> <p>It's not 100% identical -- I tried modifying the model directly in Blender but that got too messy so I ended up re-building it in Fusion 360. I've also included the F3D file so that if anybody else wants to make further changes you don't have to re-do everything from scratch like I did.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Original Prusa i3 mk3S</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.2mm</p></div> <p><strong>Filament:</strong> eSun PETG Black Post-Printing =============</p> <p>One of the holes for the nuts (the one that's at a 45 degree angle) is a little tighter than the others. I was going to change it but I realized it's helpful because that nut is "upside down" and in my previous print it had a tendency to fall out every time I had to remove the fan mount from the printer. To get it to fit into the hole and stay in place, I put a screw through the hole (before attaching it to the printer) and tightened the nut down.</p> </p></p> Category: 3D Printer Accessories
