🧩 Overview
This is a simple yet effective window limiter designed to allow only partial venting of a window – just enough for air circulation, but not enough for a curious cat to slip through.
🛠 How it works
The main arm blocks the handle from being fully rotated into the full vent position.
A thumb screw (removable peg) allows you to temporarily disable the limiter – perfect when you want to open the window fully.
It’s mounted with just one screw into the window frame or adjacent wall (use screw anchors if needed).
🖨 Printing Info
Supports imho needed – I recommend printing it flat on the side.
PETG or ASA recommended for desired durability.
🏠 Compatibility
Designed for European-style tilt-and-turn windows with outward-opening vent positions, but can be adapted for other styles too.
🐱 Safety Note
Always supervise your pet and make sure the limiter is securely installed. This is a physical barrier, not a guarantee.
