I designed this air scrubber to use a minimum of special parts. Build it today, no magnets, brass inserts, or high performance fans required! Read here about why you should have an air scrubber: https://github.com/nevermore3d/Nevermore_Micro#about-the-nevermore-micro Why pick this model: Massive filter volume, 2-3x more than the competitionIf you have a PC case fan and access to Home Depot you can build this model todayLarge filters and novel airflow path reduce static pressure and enable the use of PC case fans124x60mm footprint fits inside a Bambu, Prusa, or Voron enclosurePrints on a single build plateDoesn't require heat set inserts or exotic hardwareFusion360 CAD files are available, remixes welcomedSupported HEPA filters: Preferred:86880/MC-V194H vacuum filterUse "filter_caddy_110x74x21.stl”Preferred due to high surface area and integrated gaskethttps://www.amazon.com/gp/product/B07RM31JCH/Backup: 8040 vacuum filtersUse "filter_caddy_82x41x14.stl”https://www.amazon.com/gp/product/B0782T7L6P/Home Depot alternative:Any furnace filter, cut to size and mounted in a printed frameUse “furnace_filter.stl” with "filter_caddy_110x74x21.stl”Upgrade to a vacuum filter laterSupported fans: Preferred:3x 40x28mm axial server fansUse “axial_fan_caddy_40x28.stl”Preferred due to high static pressure and reliable qualityThese are available cheap on the used market from decommissioned servers Search on Amazon for “4028 fan” and find a 10 pack with reviews complaining that they're dusty and have the wrong labels https://www.amazon.com/s?k=4028+fan40x20mm fans will fit but I’m less confident about qualityBackup:2x 5015 blower fansUse “blower_caddy_52x15.stl” and “blower_duct_52x15.stl”https://www.amazon.com/GDSTIME-Brushless-Bearing-Cooling-Extruder/dp/B0B1V6JTB8Alternatives that you might already have in a drawer somewhere1x 120mm or 92mm PC fanUse “axial_fan_caddy_120x25.stl” or “axial_fan_caddy_92x25.stl”Upgrade to a server fan laterActivated carbon (optional): https://github.com/nevermore3d/Nevermore_Micro#nevermore-3d-printer-carbonPrint settings: This is a big model, one wall and 5% cubic infill will print fasterFilament: I prototyped in PLA, you may want to use PETG or ABS if printing high temperature materialsWiring: Drill a hole in the wall or floor of the enclosureInstall wirestodo: add instructions for normal peopleAirflow measurements todo: measure volumetric flow and compare fan and filter configurations Change log 2023-08-21Initial release2023-08-22Added clearance for wiring to the 5015 blower parts2023-08-24Added an all-in-one .3mf fileAdded CAD files2023-08-25Added guidance on filament selectionHow to contribute: Post your make, it keeps me motivated to improve the model when I see people using it!
