80mm Fan Adapter to 2" ID Hose

thingiverse

A very smooth transition to a high-performance fan adapter, designed to seamlessly attach a 2" I.D. hose with minimal turbulence in mind, features an internal cone for optimized airflow. Print two units if you want to achieve maximum efficiency by placing the fan inline. This adapter has huge potential for custom applications, such as creating a tractor cab defroster - although precise calculations are still pending, it's likely that the design can be scaled up or down to accommodate different fan sizes. Note: The original model was repaired and merged into a single contiguous solid, resulting in a new STL file. This was accomplished on December 31st, 2019.
