Solder Fume Extractor Fan

prusaprinters

<p>This is a soldering fume extractor fan I designed heavily inspired by work by the user <a href="https://www.thingiverse.com/thing:1436781">koensmelt</a> who was in turn inspired by <a href="https://www.thingiverse.com/thing:69729">sneakypoo</a> over on Thingiverse. The biggest difference with mine is the size. This is intended to mount a 12v 80mm fan instead of the larger fan in the original designs.</p> <p>Apart from this I remodeled all the rest to fit a smaller fan adding my own personal touches like:</p> <ol><li><b>Knob:</b> mostly because I couldn't design one as nicely as the original designs.</li> <li><b>Hood:</b> I simplified the hood shape.</li> <li><b>Stand:</b> it's similar in profile although smaller. I also beveled the interfaces to give more clamping surface area.</li> <li><b>Power:</b> I have a little add on if you want to add a switch and plug. This part is optional.</li></ol><p>Part Used:</p> <ol><li>Mechtronix 12v Axial Fan (F8025X12B-FHR-EM).</li> <li>Switch (uxcell Latching Metal Push Button Switch 12mm Mounting Dia 1NO 6V Red LED Light High Flat).</li> <li>Barrel Jack (5.5 x 2.1 MM 5A DC Power Jack Socket)</li> <li>Power Supply (Chanzon 12V 0.5A 6W AC DC Switching Power Supply Adapter).</li> <li>M3 x 40mm screws and matching nuts.</li> <li>Activated carbon sheet (I bought a sheet of this stuff from Amazon a while back). The dimensions for this is 80mm x 80mm and there's a lip inside that will retain the material without need of fasteners.</li></ol><p>Future idea: replace the plug assembly with a battery pack to eliminate cord hassles.</p> <h3>Print instructions</h3><p>I was able to print all the parts of this without supports.*</p> <ul> <li>Exception: the part for accommodating the plug and switch. I did the default lattice supports on it and it was fine. This part is optional if you just want to run the plug straight to the fan wire.</li> </ul>
