Those parts are under quite the stress normally, any drops and internal damage accumulate. Mine gave out after heavy usage for 2 years, got myself high-density 3D printed ones with extra depth and haven't had a problem since.
I have the files for them still, in case it happens again. Fortunately haven't had to use them.
