About this 3D model

I built a fume exhaust System for my Laser engraver and use a 150mm tube fan because of the high flow rate (https://www.amazon.de/gp/product/B09QHRRQTC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) together with a 100mm tube for a extractor hood from the local hardware store.
