(Mk2, the gap in the 'Latch Hook' has been reduced for more secure attachment). This is a door latch that prints well and works like one bought from a shop. It is surprisingly strong and effective. I have used it to keep our chicken coop gate shut which it does with ease. It could be used for keeping any un-secure door like the bathroom, dog kennel, gate and many more. As it is plastic it has the added advantage of not being able to rust. I printed 2x 'latch hoops' and 1 'latch hook' with a raft @ 98% infill and 0.25mm layer height. Time approx 25mins.I hope you enjoy it and fine a good use :) Thanks, ReneeCel
