Soldering fume extractor (120mm)

prusaprinters

<p>I'm sick of inhaling soldering fumes, so here is a fume extractor using recycled parts I had laying around.</p><p>Uploaded are 2 versions: one with mounting holes for M4 self-drilling screws that fix the fan to the box, and one without for hot gulueing the fan to the box. I f-up several times the position of the mounting holes, so my box ended up being made with non-used misplaced holes. Files should be correct by now.</p><p>Cover backplate is optional.</p><h3>Required parts</h3><ul><li>120mm fan, 12VDC 0.5A. Repurposed from a dead ATX PSU. Watch out for PC case fans as they are usually too weak (~0.15A and low airflow). No need for PWM, the simplest one will work. Get the metal cover plate too, if possible.</li><li>12V6W AC/DC transformer. Mine came from an old router.</li><li>Rocker switch 2 positions -&gt; <a href="https://www.amazon.es/dp/B07TCH6Q2W?tag=thingiverse09-20">https://www.amazon.es/dp/B07TCH6Q2W</a></li><li>Male barrel connector 10mm -&gt; <a href="https://www.amazon.es/dp/B07RMY12K1?tag=thingiverse09-20">https://www.amazon.es/dp/B07RMY12K1</a></li></ul><p>Screws M3:</p><ul><li>Minimum 3x, up to 6x length 10-15mm for attaching filter holder to box.<ul><li>Minimum 4x, up to 6x length 5mm for attaching cover backplate to box.</li></ul></li></ul><p>Screws M4:</p><ul><li>4x self-drilling screws for 120mm fans.</li></ul><p>Carbon activated air filter -&gt; <a href="https://www.amazon.es/dp/B00D9AS24E?tag=thingiverse09-20">https://www.amazon.es/dp/B00D9AS24E</a> you need to separate the white layer on this one, only the black part is useful for this.</p><h3>Printing tips:</h3><p>Print with supports:</p><p>Box facing down Print without supports:</p><p>Holder horizontal</p><p>Cover backplate horizontal, the widenest side (outside) facing down</p><h3>Mounting</h3><p>Fan+ to rocker switch.<br>Rocker switch to barrel connector+<br>Fan- to barrel connector-</p><p>Attach the fan firmly to the box, then mount and fix the switch and the connector.
