Description
UPDATE:
* Â There is a few more options - please check below and check fit test models for a right fit for your window !
Â
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
Â
EDIT:Â
Â
NEW! Just added a base model with swapped in and out. If your window opens inward that should fit your window  - please check the test file before printing the vent. Enjoy!
added 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):
added version for Inward Opening Window - it's a modified shape to fit a window that opens inward. Please check photo below (and in print profiles):
added version for 10mm Thicker Windows  - it's a modified shape to fit a window that's a bit thicker (mostly in europe, I think ).  Please check photo below (and in print profiles):
added version for Windows that have a smaller gap when closed with a gap - Thinner ducting. Please check photo below (and in print profiles):
Â
Â
IT'S NOT FOR AC! Â THE AIRFLOW IS NOT BIG ENOUGH FOR AC! DO NOT USE WITH AC UNIT!
Â
As it's a large thing to print, I included a test model (a slice) just so you can make sure everything  fit nicely in the gap that your window provides.

Installation videoÂ
Â
When printing it needs painted supports on the round inlet bit.Â
Don't use automatic supports as it'll put supports inside and you won't take them out.
