Diesel Exhaust with Flapper 50mm fan IKEA Lack

thingiverse

I installed an exhaust fan for my Lack enclosure, which sparked the idea of creating a unique port inspired by diesel truck type exhaust with a rain cap or flapper. Since no such design existed on Thingiverse, I took matters into my own hands and created one myself. Given that this design is tailored for a Lack enclosure, 52mm of it will be housed within the table, while 92mm will protrude above it. It's specifically designed to accommodate a 50mm fan. The method of mounting the fan will depend on your preference, but I strongly advise sealing it to the exhaust tube as tightly as possible to prevent any air leaks. The hollow section of the exhaust tube gradually tapers towards the top, which aids in increasing air pressure. To compensate for the varying weight of different fans, I drilled holes in the counterbalance or "tail" of the flapper, allowing you to add M3 screws, nuts, and washers to achieve balance. The ring serves as a bezel, providing a clean finish by encasing the flapper.
