Auto Gate Latch

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2998264.

An automatic self locking gate latch to suit a 1/2" (~12.5mm) pin or bolt. Obviously not guaranteed to be burglar proof, more suited to lighter duty applications (but surprisingly tough nonetheless). Designed to use an M4 x 25mm bolt and lock nut for the hinge.
