While slicing I found that the T-nut in the bottom did not slice correctly, making it easy to break. I loaded the STL up in Tinkercad and saw the nut wasn't actually connected to the rest of the model, so I fixed it :)
You can see the difference in how Cura treats the part in the bottom right of the screenshots.
