Exterior hinged window vent

Exhaust from outward-opening windows is troublesome, as large window gaps allow cold air to escape when the AC is on and warm air when the heater is on, and also let in rain and wind during inclement weather. This exhaust port can significantly reduce the opening size of casement windows, allowing for just a 16mm gap, so there's no need to fear wind and rain anymore

Suitable for three types of outward-opening windows: left-opening, right-opening, and bottom-opening (I'm a bit confused about left-opening and right-opening myself, please refer to the preview images to visualize it), the displayed image is the left-opening option from the print profile

There are three print profiles: 50mm, 75mm, and 100mm; choose the one you need to print. The order of print profiles may change, so please carefully verify the size you need in the details (hovering over a print profile will display detailed information; on the mobile app, after clicking prepare to print, you can select a print profile, and detailed information will be displayed below)

2025.7.8 Update: Due to the exhaust side slot being too long, material shrinkage would result in poor print quality and low strength; this update adds a grille to the exhaust side slot to improve print quality and model strength

2025.7.9 added print profile for 32mm duct

2025.12.29 added print profiles for 60mm and 70mm ducts

If you have a three-section screen window, please choose Outward-opening window + three-section screen window external exhaust vent: https://makerworld.com.cn/zh/models/1615614
