ALERT!! There's an even BETTER version of this available now: https://makerworld.com/en/models/487870
Hey folks,
I wanted to design a fume extraction ventilation system for 3D printers that could take advantage of some affordable and widely available components, be extremely flexible and work for whatever your printing setup looks like, and help keep those nasty resin fumes outside.
The fittings have a quick disconnect feature that uses 10x2mm neodymium magnets, and couples the hose firmly into position at any point you want to extract fumes from. Just install an outlet fitting anywhere you want to vent; directly on your printers enclosure, above your workspace in a flow hood, a cabinet or large enclosure you keep all your printers in etc.
This lets you quickly move the fume extractor to wherever you need it, and there's an included outlet cover with a handle that you can use to block off the outlets when the hose isn't connected.
You can print the entire thing without supports! I used Esun PLA+ and a 0.3mm layer height
Here's a video on the system

I recommend using super glue for the magnets. That's what I did and so far they're still going strong, and none have popped out.
Update 05/03/2024
WE'VE GONE PARAMETRIC BABY!! That's right, you can now download these files in glorious F3D format. I've remodeled them from scratch using the parametric tools in Fusion 360, and now you can modify til your hearts content and customize these models to your EXACTING DEMANDS.
Notable highlights of the update include:
All the parameters are commented, and there's a video that shows off everything that's been changed and what you can do now with the power of the parameters - so go watch that right now right here.
The included STLs here come with a 0.3mm tolerance built in for the magnets, so I would recommend printing the tolerance test part first and checking the fit with your 10x2mm magnets, and then adjust the tolerance parameters accordingly.
