Adjustable Vivarium Vent

These were designed to fit a 2 inch hole in 3/4 inch thick plywood for my custom built snake vivarium. Print 2 each of the vents (one for inside, one for outside). Print 1 of the covers - used to control airflow and increase / decrease humidity. Cover will snap into center hole of the vent & rotate to adjust ventilation. These fit snug into a 2 inch hole. May require a little glue to secure if you are concerned about them coming loose from the plywood.
