Honeycomb Fan Duct – 90mm hole pattern

This custom-designed fan duct features a bold hexagonal frame with a honeycomb mesh pattern for optimal airflow and protection. The center opening measures 78.5mm, making it compatible with a wide range of 80mm fan housings. The geometric cutouts not only give it a sleek, industrial aesthetic but also reduce material usage while maintaining structural strength. Designed for 3D printers or electronics enclosures, this fan guard offers a balance of functionality and style, with a flush-fit profile and screw mounting points for easy installation.
