We took a look at how our 3D-printed thruster coupling failed.
You can see in this picture that the coupling lost a big chunk on the side opposite from the direction of thrust. Basically, it cracked under the force of the thruster alone.
The amount of empty space in this printed part is clear now, and it's an open question whether the failure was related to salt or rust buildup inside these spaces.
There is mild corrosion on other parts of the thruster, about what you'd expect for 2 weeks underwater
