simple cheap particle filter

Simple particle filter with 120mm variable speed fan and vacuum cleaner hepa filter.I place it next to my printer to filter the particles released during fdm printing.suitable for small rooms. I added a 4 feet version wich makes it a bit more stable but i prefer 3 feet because they always touch the floor. I added a cable clamp to the print. the version on the photo has a glued which clamp i added later.
