This is a replacement front latch for a Bentgo lunch box. The one on my sons lunch box broke at school one day, so I made up this one to replace it. The hinges up top are thicker than the originals (the part that broke).
I printed this without any rafts or supports. I made the holes slightly smaller than the hinge rod that holds it on, then used a drill bit just smaller than the metal I used for the hinge rods to make sure they were circle and had a tight fit.
If anyone has had one of these latches break, hopefully this can get you back in business without having to get a whole new lunch box!
