Finding myself in need of a latch for a case, I designed this latch as a replacement. It printed in about 80 min. The tolerances are pretty tight and I would definitely try to find some 3mm steel pins for the hinge mechanisms as the plastic ones are very difficult to insert and not break while doing so. It uses 3mm screws for mounting to the case. It is as good as the original and Im pretty happy with the form and function, for a quick design and print job.  It was printed with PLA rapid+ on my Plus 4. Future improvements to it will be a locking latch and a couple of ergonomic design features.
