I guess there should be something said for effort. Nobody wants a lock mechanism that takes up 20% of the box space even if it is clever it's not practical. You still have much to learn, young one.
@markrichards7713 the mechanism doesnt take up even nearly 20% of the box space, its just a little corner of it id say 10% or less and its not even a bad design. Id ask you to give him a little more credit here
