Locking carabiner

I needed a carabiner I can trust, so I designed one with a lock that shouldn't open unexpectedly.

I made it so it doesn't require any support & made use of the layer orientation to keep it strong. All in all, it should be an easy print that doesn't require any particular attention.

The one shown in the picture are made of PLA & they are quite strong.

I'd appreciate any feedback to improve this design, I can export different size as well.

Enjoy ^^
