Window Ventilation Stopper is a simple 3D printable accessory designed to keep a window slightly open, allowing continuous air circulation without leaving the window fully open.

This can be useful when you want a small and constant airflow inside the room while keeping the window in a more controlled position.

Important: before printing, please check that the dimensions are suitable for your specific window frame. Window frames can have different shapes, clearances and locking systems, so compatibility must be verified before use.

For single windows, the stopper is fixed using wood screws.
For double windows, the original central metal locking piece can be removed and replaced with the 3D printed part.

The model is simple to install, but correct fitment depends on the type and dimensions of your window frame.
