3" Vent Hose Connector for 80mm Computer Fan

This Adapter fits 3" spiral ventihilation hose, commonly used for venting dryers and other similar appliances. I built a litter box ventilation system with an old computer fan and needed a way to connect the fan to the hose and the box to the hose. Its a snug fit with a slight lip so that you don't need a zip tie or clamp of any kind to keep the hose on.
