P2S Poop Bin + Air Purification System

[Background Description]

Recently, I have observed many MakerWorld users discussing the filtration and exhaust of particulate pollutants released during printing, as well as official exhaust fan kits. I identified a common issue: for filtration protection, most solutions rely on a small filter paper or filter element. For the average user, it is challenging to verify the reliability and authenticity of purchased filter elements, especially considering the prevalence of counterfeit and substandard products in online shopping

Based on this background, I designed an exhaust filtration system using automotive cabin air filters. It is compatible with 20*20CM filter elements from various brands. I used the Freudenberg CF106 filter element as a blueprint for its creation

[Product Introduction]

The product consists of:

1 P2S mounting hook

2 waste bin layer

3 filter element layer

4 fan

※ The P2S hook uses the Bambu Lab scraper's fixing screws (you can also find screws of the same specification) to attach it to the vent of the P2S waste outlet (see pictures) and secure it with screws

※ The front of the waste bin layer has embedded 6mm*3mm magnets. I have reserved many holes, so you can install magnets according to your actual needs, not necessarily all of them

※ Place the purchased filter element into the filter layer and cover it with the top lid. It is recommended to tape the top lid down, not because tape is absolutely necessary, but merely to prevent loosening

※ Use screws, washers, the waste bin, and the filter element layer to secure them together. Note here: do not overtighten the screws; just ensure there are no gaps

※ Install a 14CM cooling fan on the back of the filter element layer (see figure for effect)

When printing engineering materials such as ABS and ASA, there are not only particulate volatiles but also VOC gas pollution. I have created an activated carbon version of the air purifier, the link is as follows:
