Activated carbon filter for 120mm pc fan

pinshape

This is a straightforward active carbon air filter that uses a standard 120mm PC fan. The filter's thickness is 16mm, and you can see it in action as well as the assembly process in the video below. I also added legs to the PC fan for those who want to use it as a tabletop air purifier. The design has been optimized for a nozzle size of 0.4 inches. Here are some suggested settings: Layer height: 0.2mm Top/bottom layers: 1mm each Wall thickness: 0.8mm Infill density: 20-25%
