3D Printer 80mm Fan to 4" Printer External Dryer Vent Adapter

thingiverse

Many people find the smell of plastic from a 3D printer to be particularly noxious. Plus, <a href="https://3dprintingindustry.com/news/toxic-abs-pla-fumes-3dsafety-org-inquires-vocs-60796/">some studies have shown that plastic fumes are toxic</a>, especially to small children or people who have asthma. The only way to be absolutely sure fumes aren't harming friends and family in the house/workshop is to vent them to the outside. This adapter connects to a <a href="https://smile.amazon.com/gp/product/B071R218P1/ref=oh_aui_search_detailpage?ie=UTF8&psc=1">80mm fan</a> on one side and a <a href="https://www.lowes.com/pd/IMPERIAL-Outdoor-Exhaust-Dryer-Vent-Kit/3308238">standard 4" dryer duct</a> on the other to keep up air pressure and blow the fumes outside the house. I've been using this on my main printer for about six months now, and visitors report they can't smell anything unless they stick their nose right up to the printer. This adapter connects to any <a href=" from http://www.3dupfitters.com, ">3d printer enclosure</a> from 3D Upfitters or you can connect it to any enclosed 3D printer by cutting a hole to match most 80mm computer fans. The hose is then vented to the outside using whatever technique you prefer. I just <a href="https://www.amazon.com/gp/product/B01M17V4CO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1">bought a window insert from Amazon</a>. The downside was the 80mm fan wasn't strong enough to push the flap open, so I propped up the flap halfway. Note that venting the fumes will reduce the ambient temperature inside the printer, which could be an issue with ABS. I haven't noticed any problems, but tend to run my bed at 120.
