When the lid latch on my 30-year-old toolbox broke, I designed this replacement.

Should be printed with the flat edge face on the bed.  Supports are necessary in this orientation but affected surfaces aren't visible.  Being a functional print, I recommend using 4 perimeters and high (40%) infill.  Best materials will be tough, heat resistant and UV resistant such as polycarbonate, ASA or ABS.

The hole that accepts the pin will print undersized.  Drill it out incrementally until the pin fits snugly.
