Window / Door Limiter Lock

 When you just want to keep your window open just a little.  

My cats always ask to open and close my patio door. For me, it was unsafe to keep the door open all the time because it was made of glass. Therefore a need for a way to keep in an in-between mode.

With this, you can keep the door just open to get some air circulation in the first scale (is too narrow for a cat to go through), and in the last scale, even a big cat can use the door.

I used PLA, with 50% infill for mechanical stiffness

and a filament change in layer 35 for cosmetics reasons only

an M5 screw and nut for the axis
