Side Panel Grill Mount - Bose 601 Series II Direct Reflecting Speaker

<p>This is a replacement panel grill mount for my Bose 601 Series II Direct Reflecting Speaker. One of my speaker's original grill mounts broke cosmetically and so I modeled and 3D printed my own rather than shelling out $80 for a "new" one on an auction site.</p><p>In high school I 'rescued' a pair of Bose 601 Series II's from the garbage heap for the trouble of replacing the foam woofer surrounds. At the time I really didn't know anything about big floor speakers or audio equipment. In the years since I've become very fond of them and they've become a little worse for wear as I've moved them from place to place.</p><p>Each speaker has a left and a right and there's no difference between the left/right sides as far as I can tell. Cosmetically this grill mount model is a pretty close match to the original stock part. I did make some concessions for ease of 3D printing on the inside faces, but you have to take the covers off to see those.</p><p>In the photos the replaced panel is on the right side. Left side view added for comparison.</p><p>For those of you who use OnShape here's a link to the original CAD: <a href="https://cad.onshape.com/documents/a18d9c435ee5f9880f514456/w/4eb4a061869f7f1d117e9078/e/0a924f45720e06f104a5de38">https://cad.onshape.com/documents/a18d9c435ee5f9880f514456/w/4eb4a061869f7f1d117e9078/e/0a924f45720e06f104a5de38</a></p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p><strong>Printer:&nbsp;</strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0.3</p><p><strong>Infill:&nbsp;</strong></p><p>10% Gyroid</p><p><strong>Filament:</strong> California PETG PETG Black<br>&nbsp;</p><p><strong>Notes:</strong></p><p>This part was too large to print in one piece on my Mk3S, so I printed it in two</p><p>To ensure the best strength for the grill ribs you should print with no less than 4 walls and with bridge settings turned on.</p><p>With my Prusa I really only needed supports on the "top" 2-3 inches on the grill ribs side and around the unsupported curve of the front/rear fascia. Bridging took care of the rest. See PrusaSlicer screenshot for support locations.</p><h3>Post-Printing</h3><p>After cleaning up the support material, a little lite sanding on the faces of the split seam should be prep enough to glue the two sides together. I sanded it with a sheet of sand on a flat work surface and by moving the part, seem face down, against the paper. It is easy to sand too much off of one side/corner (so be careful), but this method does provide two fairly flat surfaces for gluing.</p><p>I used super glue (Bob Smith) to bond it together and binder clips to hold it in alignment while it set.</p><p>From there your part should be a drop-in replacement for the OEM grill mount.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Audio</p>
