prusaprinters

<p><strong>How this project started:</strong></p><p>After researching VOCs I'm still more comfortable exhausting them out of the house when dealing with things like ABS. &nbsp;I do have a really good air filter with a carbon filter, plus HEPA/carbon scrubbers inside the enclosure.</p><p><strong>Description</strong></p><p>I'm continuing to modify my NextGen enclosure, so it works for the space and setup I have. &nbsp; This is an addition to my enclosure exhaust fan design:</p><p><a href="https://www.printables.com/model/204392-nextgen-enclosure-exhaust-fan-adapter">NextGen Enclosure Exhaust Fan Adapter by AKA | Download free STL model | Printables.com</a></p><p>This filter is for fumes from PLA or PETG if you happen to have a brand that puts off an unpleasant odor. &nbsp;I had a few rolls and wanted to help clear the air a bit better.</p><p>This is NOT a professional grade air scrubber/purifier and should not be considered and effective remedy for removing toxic VOCs and fumes.</p><p>For ABS, ASA and other filaments that put off toxic fumes when printing I recommend venting out of the house/work area completely.</p><p><strong>Parts List:</strong>&nbsp;</p><ul><li>Next Gen Enclosure Exhaust Fan adapter listed above</li><li>Roomba 800/900 Replacement Filter x2<ul><li>Ex: <a href="https://www.amazon.com/MZY-LLC-Filters-Replacement-Robotic/dp/B00K7DMEJ0/ref=sr_1_4?crid=36E8IHWU3YZHF&amp;keywords=roomba+900+filter&amp;qid=1664223840&amp;qu=eyJxc2MiOiIzLjAwIiwicXNhIjoiMi42OCIsInFzcCI6IjIuNzkifQ%3D%3D&amp;s=home-garden&amp;sprefix=roomba+900+filter%2Cgarden%2C60&amp;sr=1-4">Amazon.com - MZY LLC 12 Pack Hepa Filter Filters Replacement For irobot Roomba 800 900 series 860 870 871 880 960 980 Robotic Vacuum Parts -</a></li></ul></li><li>Activated Charcoal (for fish tank or other source)</li><li>Storage container when not in use</li></ul><p><strong>Print Settings:</strong></p><ul><li>Default PrusaSlicer settings for PETG <strong>@ 0.30mm quality </strong>(PLA would probably be fine as well)</li><li>Supports: None</li></ul><p><strong>Assembly:</strong></p><ul><li>Place a layer of activated charcoal in the bottom of the printed filter module. &nbsp;Use a paper town or something similar. &nbsp;It's messy.</li><li>Shake gently to remove any smaller/loose bits (you also don't want the dust to go everywhere).</li><li>Place the two Roomba filters on the top of the printed part, push in place firmly.</li><li>The entire assembly fits into the slots on the top of the exhaust fan assembly.</li><li>When not in use, remove and place in an airtight container to help preserve the activated charcoal.</li></ul><p><strong>Change Log:</strong></p><ul><li>10-31-2022<ul><li>Added Filter Attachment_R2: Expanded lip around full bottom edge for easier placement and a better seal.</li></ul></li></ul>
