My toyhauler has three small 6x6 hatches and the latch mechanism has failed on two of them, so I modeled up a replacement. On mine, the part that failed was the small flat piece (part 2), but I Modeled and printed both parts. You will need to reuse the original spring or find a replacement. I was able to reuse mine.

I printed in PLA with 100% infill. We will see how it holds up.
