I accept the findings of the tests that have been made, and apologise for having raised a non-issue with my concern about the strength of the hexagonal infill.
With regard to hexagonal copyright which MakerBot might hold, would it not be possible to consider octagonal (8 sided rather than 6 sided)? That would give a uniform pattern.
Alternatively, provide some sort of editor capability within S3D so that the user can define their own infill design. Maybe some sort of point-and-drag a line across an an editor area comprising of pixel boxes, so that the S3D infill can follow the line as it does the infill. I'm sure there must be lots of scope there for a developer to be inventive
