Magnetic Quick-Disconnect Ventilation system for Resin 3D Printers

prusaprinters

<p>Hey folks,</p><p>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.<br><br>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.<br><br>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.</p><p>You can print the entire thing without supports! I used Esun PLA+ and a 0.3mm layer height</p><p><strong>Here's a video on the system</strong></p><figure class="media"><oembed url="https://youtu.be/zk9KcGAH_Zc"></oembed></figure><p><strong>What you'll need | </strong><i>Affiliate Links &lt;3</i><br>4" Inline Fan - <a href="https://geni.us/E31MO">https://geni.us/E31MO</a><br>4" Vent Hose - <a href="https://geni.us/DSqwco">https://geni.us/DSqwco</a><br>Plank of wood that fits your window or an AC Window Kit <a href="https://geni.us/AEv78e">https://geni.us/AEv78e</a><br>10x2mm Neodymium Magnets - <a href="https://geni.us/i8uAI69">https://geni.us/i8uAI69</a><br>M3 Bolts (I used a mix of M3x8 and M3x12) - <a href="https://geni.us/TVsnB">https://geni.us/TVsnB</a><br>80mm Hole Saw (with teeth, not the diamond type) - <a href="https://geni.us/xPTj">https://geni.us/xPTj</a><br>Insect screen mesh - <a href="https://geni.us/17df2">https://geni.us/17df2</a><br>Hose clamps - <a href="https://geni.us/hRDvaG">https://geni.us/hRDvaG</a></p><p>Tip: Depending where you are it may be significantly cheaper to source the insect screen mesh and hose clamps locally. For most of the other parts I found better deals on ebay so check there as well, but thank you for using my affiliate links.<br><br><strong>Recommended tools</strong><br>Power Drill<br>Staple Gun<br>Hand saw</p><p><strong>Update 25.09.22</strong><br>I've added variations on the parts for those of you who wish to embed the magnets in place during printing rather than glue them in. They're provided in both 0.2 and 0.3mm layer height variants so just download the ones for your preferred layer height.<br><br>If printing the original files 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.</p><p><a href="Buy me a coffee?">https://www.buymeacoffee.com/onceinasixside</a></p>
