This is a printable latch for the standard plastic ammo box or crate, (these days popular for camping). The original latch seems to be manufactured from a glass filled plastic, is brittle and breaks easily, therefore I have created this printable model to replace broken latches. I suggest to print the part from a tough plastic like ABS or ASA (if the box will be exposed to UV frequently) . Orient the part horizontally (see image) for the printing process. Its dimensions are a bit larger to compensate for a filament that is not glass filed, but the latch functions perfectly.

Print solid or 0 infill. Wall thickness is 3.2mm good for 0.4 nozzile.
