Series S Hepa Filter Super Special Edition

prusaprinters

<p>Liked the idea of scotty's air filter, and since the 120mm profile and room for a battery bank use way too much plastic either way, figured id fix a couple issues i didn't like with it and use it as my main soldering fume extractor. Like it not even being able to run crysis, or having hepa, or being swag enough, so i started poking faces starting from <a href="https://www.thingiverse.com/thing:4661215">https://www.thingiverse.com/thing:4661215</a> noticing there weren't quite enough sketches, The source i included successfully has over 100 sketches now for maximum headache :) With 13 hour print time for the main body im done now that i made mine work, though i did fix a few issues i ran into afterwards like the side ridges and button depth but didnt test. I included notes at the end of what I would've ideally fixed if i had the time to spend on this design.</p> <p>Other Items You may need:</p> <ul> <li>120mm fan with over 2lollipops of pressure u wont be pulling much air through those hepas</li> <li>3 18650s and a bms if u want to make the battery bank</li> <li>Roomba Hepa filters (some of hte generics are different size, i use streight clips to cut the fitting on the hepa filter back 1mm for the ones i use to get a good fit)</li> <li>a pi4 if u want a pi4 ofc, the internets say 4 or 8gb model can do streaming fine</li> <li>input and switch for w/e kind of power you decide on (definately resize the feature on back to match yours)</li> <li>Guide for carbon filters if u don't want to buy new ones <a href="https://www.thingiverse.com/thing:4811349">https://www.thingiverse.com/thing:4811349</a></li> <li>Sloppy 3s 18650 holder i zombied together <a href="https://www.thingiverse.com/thing:4811344">https://www.thingiverse.com/thing:4811344</a></li> <li>m3 bootsie <a href="https://www.thingiverse.com/thing:4810946">https://www.thingiverse.com/thing:4810946</a></li> <li>For the hepa u need the Filter_Mount_v2.stl and Fan_Mount_Bottom_v2.stl from <a href="https://www.thingiverse.com/thing:4095912">https://www.thingiverse.com/thing:4095912</a> (Half of the ones ive printed click in tight and fine, other half i hotglued the seam w/ a clamp.</li> </ul> <p>Changelog:</p> <ul> <li>Make front cover attach without evil glue ( CRITICAL FAILURE, gave up and cried)</li> <li>Make it so it can run crysis (successful with cloud rubbish on pi4b)</li> <li>Add 3s battery bank with mounting point for power</li> <li>Add little ridges to support middle</li> <li>Added little recessses for 12mm sticker feet.</li> <li>Added 3mm hole for 4th foot on bottom face since pi was in the way.</li> <li>Halo Super Special Edition insert</li> <li>Swapped around back for the random stuff i had to wire it up in my box.
