Found a different Carlson latch here... almost the same, but that was for the release button on the side, but mine is on top. This isn't a remix since the original was in F360 and my trial is up, so it was newly designed in FreeCAD.
I also widened the surface that contacts on the inside of the latch (the T shape sticking up in the back), hoping that this will improve the design and make it less likely to break in the future.
Update: This part lasted 3.5 years before it broke - far beyond the original. And you can just print another!
