IKEA Platsa 120mm fan with filter

prusaprinters

<p>To get rid of the smell and fumes from my Mk3s in the IKEA Platsa enclosure I designed a fan and filter holder to use with my Corsair ML120 fan and some active carbon filter (used for kitchen fans).</p><p>It will work on any enclosure wall that is 18mm thick. Without the funnel it will probably work on others as well.</p><p>I'm running the 12V fan from a 11V PSU off an old random device I found and soldered on a suitable connector on it, and then connected it to an IKEA Trådfri outlet controlled with IKEA Trådfri motion sensor. So whenever the printer is moving, the fan and lights are running :)</p><p>Installation instructions</p><ul><li>Drill a 111mm hole in the inclosure.</li><li>Press-fit the funnel in place from the inside (fan side)</li><li>Mount the fan and the fan holder in place with longer wood screws. The holder is held in place with the same screws as the fan. Keep note of the notches for oriantating the fan cover correctly with the fan cable. The funnel will be kept in place by the fan holder.</li><li>Mount the fan cover</li><li>Install the filter holder with shorter screws on the outside (the holes are a few mm offset from the fan screws).</li><li>Cut some filter material and press in place with the filter cover. Use a filter with 8-15mm thickness. I am currently using a 15mm thick filter that is squished in place by the filter cover. Thinking of adding another layer of filter for smaller particles but the fan is having a tough time pushing air through it as it is now.</li></ul><p>The fan needs to be running at full speed in my case in order to get any flow though the filter. But it seem to be sufficient to get rid of the PLA-smell in my room with my current fan and PSU setup.</p><p>For building the IKEA Platsa enclosure, check this out: <a href="https://www.prusaprinters.org/prints/49903-prusa-ikea-platsa-single-dual-enclosure">https://www.prusaprinters.org/prints/49903-prusa-ikea-platsa-single-dual-enclosure</a></p><h3>Print instructions</h3><p>Printed in Prusament orange 0.2mm layers.</p><p>&nbsp;</p><p>&nbsp;</p><p><strong>EDIT 2021-03-30:</strong></p><p>STEP files added.</p>
