> I guess you could say that it was a very well-sealed camera.

Well, it did fall off the seal. Though that's not very typical.

Why wouldn't it be 3D printed? Not strong enough? I assume it's a fairly specialised item and shape.

Even if it was initially 3D printed, there is a fair bit of CNC machining that goes into making it a final useable product

Oh yea CNC'd is more likely. A 3D print would never survive.
