3" Terrarium Vent

3" vent for terrariums, tubs or whatever you may use to house various reptiles or insects. These are designed to work with a 3" hole saw.I recommend printing with PETG if they will be used on anything that is wet or high humidity. ** Small note **I printed these acrosse a few different printers. They all were sucessful, however I did have to run a small flat head screwdriver through the threads on one of the prints as it was difficult to twist together. After doing that it functioned just as it should. Big thanks goes out to a buddy that helped get the profile right to make these spin together as the smaller vents do!
