Adjustable Window Tilt Lock

This is a locking mechanism for windows / garden doors.

I made this to be able to open my window just a bit, so the cats can´t escape ;-)
It can also be useful, when drafts are pulling your windows closed.

The moving parts are designed to be connected by a 3mm (5/32 inch) rivet or screw. When using a screw, I´d recommend using a lock nut / stop nut.
The mounting screws are also 3mm in diameter.

SolidWorks file included for modification.

UPDATE: Riveting hole enlarged by 0.2mm for easier insertion ob bolt/rivet.
