I love the design, but needed the latch part to be a bit longer to be more stable against a cat trying to butt its way into the bathroom to destroy the toilet paper.
Ninja_Lock_-_Short.stl is the original stl file, and has a better arm angle for my doors,
I used tinkercad to extend the latch for a better fit.
It holds the door about 2 inches ajar, enough for airflow without letting a cat in.
The author remixed this model.
