Fan shroud for "Noctua LH-L9a-AM4" CPU cooler in "Kolink Rocket" case

thingiverse

This is a fan shroud designed to draw cold air from outside into the CPU fan, utilizing the side panels for airflow. It should fit snugly without any need for mounting hardware or tape. I created this design specifically for the Kolink Rocket mini-ITX pc case with a 92mm Noctua fan on top of the LH-L9a-AM4 cooler and an ASUS ROG STRIX B450-I board. However, it should also fit well on other boards. To adapt this shroud to different cases and fans (specifically top-down blower style), you'll need to experiment with values in Customizer or OpenSCAD. When modifying the design for your specific needs, be mindful of wall thicknesses - the outer and inner sides may not be perfectly parallel, which can cause issues during slicing. Ensure that layers are properly aligned by checking the layer view in your slicer software.
