Fan for Coolie Vacuum Pump

thingiverse

If you have a "Made in China" rotary vane vacuum pump like they are sold on eBay for under $100, you may experience the motor fan failing due to the plastic aging, becoming brittle and ultimately breaking. This is a replacement motor fan that lets you repair the pump and get many more years of service from it. It is not 100% identical, but easy to 3D print and fully functional.
