Carbon Air Filter

thingiverse

I was affected by ABS fumes and sought an affordable activated carbon air filter. Choosing a US$8 automotive model, I found that it was larger than my print bed, necessitating a holder and fan mount. To accommodate the filter on my 155x155 (6") printbed, I created a model with four cut-up STLs and an OpenSCAD file, designed for use with a 120mm fan. The design is parametric, allowing customization if needed. This project led to the creation of my FanLib OpenSCAD Library, accessible here. The filter may also be suitable as a soldering filter, though it has not been tested yet. Since implementing this solution, I have experienced relief from previous nose and sinus issues. Printing the four pieces can result in some splitting, which can be remedied with ABS goo or acetone. Assemble the filter holder by sticking the pieces together and attaching a 120mm fan with a rubber quiet-pc seal. Ensure proper air flow direction before securing the fan. Insert the filter and power on for clean air. To enhance stability, add rubber bumpers if needed. Initial results are promising, and I will update later.
