Yoopai Enclosure Vent Adapter

This is a vent adapter for a Yoopai enclosure. I made this for the size large tent. You will install this adapter on the enclosure in order to hook up a 4 inch duct. The donut looking ring goes on the inside of the enclosure to seal and secure the two parts. You will need 4 m3x12 screws and boltsInside diameter of the vent adapter is 71.6mm, ID of the back plate is 70.3mm May fit other enclosures
