FAE for mushroom Martha tent 3d printed window vent #mushrooms

To help with FAE (fresh air exchange) on my mushroom Martha tent I 3d printed a custom window air vent! This is not the first thing I have printed either, I printed a jig for cutting the holes for my filter patches. A holder for the humidifier hose and am looking for my next project
