<h3>Introduction</h3><p>Minimalistic solder fume extractor with 120mm fan and two active coal filters. Easily prints in three separate parts and slides together into a space efficient and sturdy package. The bottom is fastened with two countersunk M3 screws and threaded inserts for longevity and easy filter changes.</p><p>The fan holder is designed to accept Noctuas anti-vibration mounts, which is why there is such a big counterbore. Normal fan screws or machine screws should also work.</p><h3>&nbsp;</h3><h3>Parts list</h3><ol><li>3D printed parts (I used PETG filament, PLA is also fine)</li><li>120mm high airflow fan, e.g. <a href="https://noctua.at/en/nf-f12-industrialppc-3000-pwm">Noctua NF-F12 industrialPPC-3000</a></li><li>2x Active Coal Filter, e.g. <a href="https://www.distrelec.biz/en/active-coal-filter-rnd-lab-rnd-560-00157/p/30088281?track=true&amp;no-cache=true&amp;marketingPopup=false">RND 560-00157, from DISTRELEC</a></li><li>DC Power Jack 2.5x5.5mm, e.g. <a href="https://www.distrelec.biz/en/power-jack-5x5-5mm-straight-rnd-connect-rnd-205-00906/p/30129726?track=true&amp;no-cache=true&amp;marketingPopup=false">RND 205-00906, from DISTRELEC</a></li><li>DC Power Plug 2.5x5.5mm, e.g. <a href="https://www.distrelec.biz/en/dc-power-plug-5x5-5mm-straight-rnd-connect-rnd-205-00901/p/30129721?track=true&amp;no-cache=true&amp;marketingPopup=false">RND 205-00901, from DISTRELEC</a></li><li>Power Rocker Switch, e.g. <a href="https://www.distrelec.biz/en/power-rocker-switch-spst-on-off-rnd-components-rnd-210-00553/p/30109760?track=true&amp;no-cache=true&amp;marketingPopup=false">RND 210-00553, from DISTRELEC</a></li><li>2x M3 Threaded inserts, e.g. <a href="https://export.rsdelivers.com/product/rs-pro/14591/rs-pro-m3-brass-threaded-insert-diameter-4mm-depth/0278534">RS PRO 278-534, from RS Components</a></li><li>2x M3 x 8mm Hex Socket Countersunk Screw, e.g. <a href="https://export.rsdelivers.com/product/rs-pro/din-7991/rs-pro-m3-x-8mm-hex-socket-countersunk-screw-black/0281388">RS PRO 281-388, from RS Components</a></li><li>DC Power Adapter with suitable specifications for the selected fan</li><li>Appropriate wire</li></ol><h3>&nbsp;</h3><h3>Post-printing</h3><ol><li>Gather all required parts, see parts list below.</li><li>Brass threaded inserts are melted into the plastic using a soldering iron.</li><li>Insert and wire up the power plug and switch. I recommend wiring in a 3-/4 pin fan connector, rather than wiring the fan directly into the circuit. This makes it easier to change out the fan later, if it breaks or you need a higher RPM fan.</li><li>Attach the fan to the fan holder, using Noctua anti-vibration mounts or screws.</li><li>Insert the fan holder, with fan, and two active coal filter into the frame.</li><li>Attach bottom using two M3 countersunk screws.</li><li>Wire in the power plug to a DC power supply, suitable for the selected fan. 2.5x5.5mm is a fairly common DC barrel power plug, so you might already have a suitable power supply with this plug already laying around.</li><li>Plug in and enjoy a healthy soldering environment!</li></ol><h3>&nbsp;</h3><h3>Addendum</h3><p>I am working on a new iteration, which incorporates PWM control, RPM read out, HEPA filter and battery power. Currently having difficulties sourcing a fitting HEPA filter.</p>
