Active coal filter holder for 120mm computer fan

thingiverse

Here's a better solution to eliminate unpleasant odors: 3D printers melt plastic, which isn't pleasant. To tackle this issue, I've always had an active charcoal filter near my printer. After relocating the printer to a new location, it was time to design a more effective filter holder. This one is oversized with ample space for the filter material. I utilize an active charcoal sheet specifically designed for oven fans. A sheet costs only a couple of dollars and lasts for years, boasting a thickness of 7 mm. At the bottom of the holder lies a standard 120mm computer fan that draws air in through the filters, causing dust to collect on the outside of the filter. The files contain the complete holder assembly as well as the holder cut into four pieces. I assembled it by gluing the pieces together.
