72mm exhaust fan for 3d printer to 3" hose

exhaust your ABS fumes outside with this 3" hose adaptor. The fan goes on the outside of your case and connects to the hose with a ziptie. The other end will ziptie to a 90 degree connector on a 2" PVC connector for venting outside.
72mm fans are often found on power supplies for computers. Make sure to avoid the capacitors if you take a power supply apart! They can hold a charge for a very long time and can be very dangerous!
