<p>Geodesic Dome grill for Air purifier to reduce noise. The original 41 fin grill adds a lot of noise. This grill is almost as quiet as having no grill.</p> <p>v2 improvements over the first version:</p> <p>Thinner bars</p> <p>Rounded bars</p> <p>Rectangular fan opening with chamfer.</p> <p>The last change, making the base plate rectangular, significantly reduced the noise.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</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>200</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>10%</p></div> <p><strong>Filament:</strong> Overture PLA Matte Gray</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Easy print with PLA.</p> Supports from build plate only with a 25 degree overhang threshold. Supports needed only for the center region. <p>Use enclosure.</p> <h3>How I Designed This</h3> <p>This was made using onshape to cut the base plate from the 41 fin model, then I mated it to a geodesic dome designed by Wolfgang Walden (search youtube for the how-to). I enlarged the center region to match the fan box profile and rounded the bars that make up the dome.</p> </div></p></p></p> Category: Other
