Strong latch

This latch nearly doubles the length from one part to another comparing to ordinary latch. So it requires much less force to close the latch. This is great for parts that use seal. The mechanism is hidden inside the box so it looks better.

Print it without "catch" and move the 1st axis (pos[0]) closer to 0. This will keep persistent force when closed. Otherwise it will be loose. Tune "gap" to print it in place.
