Description
Remove harmful fumes and VOC from the air to keep you, your family and your pets safe.
This mod uses proven HEPA and activated carbon filters with powerful 5015 radial fans to achieve a 5.5x improved filtration over the axial version!
Complete 6.3mm magnet conversion.
Optional heat set insert version of the HEPA housing to secure the top of the bento box to the side panel, ensuring bed clearance for additional safety. Recommended to use in combination with m4 washers under the base to keep it straight and not leaning toward the bed if your prints are warped. Also reduces vibration. Use the drill template to drill the hole and use an M3 screw to secure it. I originally ripped the M3 heat set insert out because I eyeballed the position of the hole and it didn't line up well, but was still able to secure it using a longer M3 screw and a nut, and fine tuned the base position by putting m4 washers underneath it. The drill template was designed afterward to make it easier for you (won't fit k1 max). Alternatively you can just print the version without the heat set insert, drill a hole anywhere through the panel and housing at the same time and use nuts and washers.

VOCs (Volatile Organic Compounds) generated from 3D printing are known to cause severe health issues and even cause cancer in some cases.
A study from 2013 of ultrafine particle emissions from desktop 3D printers (2013) is a good start to understand the importance of your filament choices and the printer's environment.
