Centrifugal Fan

thingiverse

This experimentally designed fan isn't intended for long-term use due to slight vibrations from misalignment and lack of bearings. Enhancements are sought without relying on vitamins. The dimensions aren't optimized for maximum airflow, with fan characteristics based on mental simulations influenced by distractions like The Walking Dead. For actual centrifugal fan design insights, check out these PDFs: http://www.wesellfans.com/pdf/underStanding-Centrifugal-Fans.pdf and http://www.ijaet.org/media/0001/5PARAMETRIC-STUDY-OF-CENTRIFUGAL-FAN-PERFORMANCE-EXPERIMENTS-AND-NUMERICAL-SIMULATION-Copyright-IJAET.pdf. When printing the Fan Case, only generate support for it as the necessary support for the Fan Blade is already included in the .stl file. For optimal results, print the case in PLA due to ABS's tendency to warp on tall and thin walls. Photos demonstrate this issue. You will require an appropriately sized motor, with mine being a randomly found one without markings. Upon starting the fan, ensure the Blade rotates counter-clockwise; reverse leads if not.
