A1 mini filter

Created a small filter housing for a 40mm fan for my Bambu A1 Mini.There is always a slight smell coming from printing PLA or PETG, as well as small particles that are bad for health. I'm sure this is not the most effective way of filtering, but it does help reduce some of it.There are very limited vibrations coming from the filter. I printed multiple calibration pieces before and after with no differences, and it seems to have no effect on the print quality.For now, I'm using a 40x20mm fan, but I'm planning to change this to a 40x10mm fan for reduced weight.Using multiple layers of active carbon matting including a vacuum dust filter Used 2 M2 brass inserts and screws for the top connection. I used a glue gun with a PLA stick to “weld" the two parts togheter, cant be printed in one go due to strength issues Im a complete beginner with CAD software so the STL files are a mess, if you want them please let me know and i'll try and upload them.
