balcony door latch

I made a replacement for our WERU balcony door latch. the door would open itself on windy days so I made the latch bigger than the original one. So far it works great.

the original part has a little cylinder that clips into the door but it works fine without it and then I have a flat surface to print it on

update to V3:
after some time to test and improve the design, the V3 works much better for me
