<p>Air purifier for SLA printers. Circulates the air inside of the SLA printer hood, with carbon filter to absorb the resin fumes generated during printing.</p> <p>You need:</p> <ul> <li>40mm 5v fan.</li> <li>Thin carbon filter. I used cuttable Sini vacuum cleaner odor absorbant, that is available in Finland. Its 1mm thick. I used two layers.</li> <li>4 X AA battery pack.</li> <li>4 X AA batteries. I use rechargeable batteries.</li> <li>Optional: 40mm Laminar Flow Fan plate <a href="https://www.thingiverse.com/thing:432630">https://www.thingiverse.com/thing:432630</a></li> </ul> <p>The bottom part is hold only by friction and battery pack has some weight. In the future I will refine the part by making claws that connect to the sides of the middle part. But for now hold it from the bottom.</p> <p>I use this in Elegoo Mars 2 Pro.</p>
