Window lock

thingiverse

A versatile window latch system commonly used in Europe, this design allows for easy installation by attaching the mount to the wall beneath the window frame. Next, an adjustable arm (ranging from 8cm to 14cm in length) is attached to the mount, followed by securing the lock directly to the window itself. To secure the window in place while open, simply slide the adjustable arm into the lock mechanism, effectively preventing any unwanted movement. This model's design minimizes the risk of plastic shrinkage issues since all components will contract at an identical rate. Additionally, users can freely scale up or down according to their needs, as long as each component is resized uniformly.
