This is a sleek duct for 40mm fans, perfect for attaching to a 3D printer or similar device. The goal is to minimize wind noise by crafting an aerodynamic design that optimizes airflow. While it may not make a significant impact with high-powered fans, its effects are particularly noticeable on smaller devices like 3D printers. Its unique shape bears a striking resemblance to a plane turbine's sleek profile. Designed specifically to accommodate M3 bolts, this duct is a stylish addition to any setup.
