Central Vacuum Muffler / Silencer

prusaprinters

<p>Not sure how many people are looking for vacuum mufflers on Thingiverse, but if you are, you've come to the right place!</p> <p>I somehow managed to lose mine so I designed and printed a new one. To my surprise, it works pretty well! The airflow is not noticeably restricted yet the noise dropped from 90 dBa to 79 dBa. See it in action here: <a href="https://www.youtube.com/watch?v=wev-VcMSJIU">https://www.youtube.com/watch?v=wev-VcMSJIU</a></p> <p>Note: I had the inlet open in the garage for testing so the real world sound levels are lower when you're vacuuming in the house.</p> <p>This fits over a 2" pipe exiting the vacuum canister. I've included the Fusion 360 files if you would like to modify for your own vacuum. I used S3D for the slicing and included the supports for the bottom part. You shouldn't need supports to print the internal structures as I have tried to limit the overhangs to 45*.</p> <p>Please excuse the rough nature of the print in the photo. It survived 2 power failures and running out of filament once. But it's a vacuum part so I wasn't overly concerned about cosmetic appearance.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>CR-10S</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>Quick and dirty - it's a vacuum!</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Printed fast with a 0.8 mm nozzle and 0.4 mm layer height.
