3in window vent

Just need to guide the air out of my window using my 3in hose, please keep the settings: Top Layers 0, Bottom Layers 0 to have a mesh grid at the bottom Note: the outer diameter is more like 2.5in because you can easily tighten the hose to fit, but it would be hard to stick it inside the hose if it is too big, scale it if you need to fit a larger hose
