<h2>Version 2 of HEPA and activate carbon filter (refillable)</h2>Filter for closed Bambu Lab printers that combined HEPA and activated carbon (EAC- Extruded activated carbon). I have remix my <a target="_blank" href="https://makerworld.com/en/models/49753#profileId-51576" rel="nofollow noopener">old version</a> improving:<ol><li>increased capacity of carbon pellets (more than 30%).</li><li>improving slide fitting of parts</li><li>removed all print supports</li><li>ad a new “two finger remove” (better with two hands)</li><li>moved infill direction of grid for increase mechanical resistance.</li></ol>&nbsp;Use a temperature resistant filament like ASA or ABS (maybe PETG), PLA only for first stage of testing (keep chamber temperature of printer under 40°C).&nbsp;IMPORTANT: remember to adjust the shrinkage according to your ASA/ABS filament!!<h3>bill of Material (amazon.it)</h3><ul><li><a target="_blank" href="https://www.amazon.it/dp/B07HHQKJ4G?ref=ppx_yo2ov_dt_b_product_details&th=1&_encoding=UTF8&tag=errelle-21&linkCode=ur2&linkId=aed3f900a91119a53db7886f9d788013&camp=3414&creative=21718" rel="nofollow noopener">HEPA filter</a> (same filter of <a target="_blank" href="https://makerworld.com/en/models/12786#profileId-24358" rel="nofollow noopener">bentobox</a>, you can search hepa filter for robot iLife, V3, V3S, V3S Pro, V5, V5S, V5S Pro).</li><li><a target="_blank" href="https://amzn.to/3M9IBCL" rel="nofollow noopener">activated carbon pellets</a> - (use only ACID-FREE activated carbon pellets), or use pellets of original Bambu Lab carbon filter.</li><li>cutter</li><li>if you prefer, strip for pull it out</li></ul><h3>assembling</h3><ol><li>cut the side excess of HEPA filter with a cutter</li><li>glue the strip (not necessary)</li><li>insert HEPA filter</li><li>insert activate carbon pellets (EAC)</li><li>insert slide cover on EAC</li><li>slide box EAC onto HEPA filter box</li><li>put filter inside printer</li><li>enjoy</li></ol>&nbsp;<h3>considerations</h3>New capacity of my design box for activate carbon is about 38g. Original Bambu Lab filter is 80g and it is guaranteed for 1440 hours (60 days).So probably it will be necessary to change the activated carbon within 680 printing hours (28days).&nbsp;<h3>tips</h3>Set chamber fan at 50% of power in filament ASA/ABS start gcode with "M106 P3 S130" command.&nbsp;
