Active coal filter holder for 120mm computer fan

People often complain about 3D printers melting plastic, releasing unpleasant odors. To overcome this issue, some enthusiasts rely on an active coal filter placed near the printer. However, a better setup is necessary when moving to a new location. A large filter holder was designed with ample space for active coal sheets. These sheets are typically used in oven fans and cost only a few dollars each. They last for years and are 7 mm thick. At the bottom of the holder, a standard 120mm computer fan draws air through the filters, collecting dust on their outer surfaces. The files contain the complete holder assembly, top section, and the holder divided into four pieces. The design allows users to assemble it from individual parts and glue them together securely.
