Window Vent (through locked window)

UPDATE:* There is a few more options - please check below and check fit test models for a right fit for your window ! This is a 100mm vent for UPVC windows that can be locked when slightly open. It vents all the way out , so no need to open the window wide to put a hose out, at the same time the window can still be locked making sure it's secure .When printed in white, it's hardly noticeable from outside (thus my photo in black filament).It's made in a way that the rain won't get inside and any water drains out the front.I printed mine in PETG.Outside diameter of an inlet is 100mm EDIT: Just added a vent that fits (at least some) windows that open inwards. There's a fit test file as well, so you can check if it fits your window (Look for Inward Opening files)added 150mm version too and few othersadded version for Single Window - it's a modified shape to fit a window that takes up a whole opening and opens outward. Please check photo below (and in print profiles)
