Air purifier

I created this purifier to put in the housing of my 3D printer because I print mainly in ABS and it seems that the fumes are toxic. This air purifier is mounted with a HEPA filter composed of an activated carbon filter, with a 120mm fan, and 4 threaded rods, diameter M4 mm, length 23 cm. I tested it with smoke, and it sucks very well. Here is the link for the filter: https://www.amazon.fr/DIKI-purificateur-rechange-v%C3%A9ritable-efficacit%C3%A9/dp/B08CXPX7P1?pd_rd_w=OlxPQ&content-id=amzn1.sym
