A while ago I came up with something when trying to tie a cargo net with a single line. It was a pattern that also seems like it would work very well for 3D printing. It allows for hollow spaces in larger models, while maintaining strength, and giving roofs plenty of support material. Or the internal walls would naturally add more strength if they're multiplied and follow a "100%" infill model, since the pattern also works like a fractal going inside itself.

I however don't have the skills needed to write code or spell out the exact math that would generate such a pattern, make it reliable in all cases, and especially for outputting to G-code. So I'm just looking to connect with someone who has those skills. Unless someone else wants to take up the problem as well.

The main concept is just keeping one single line going with each layer where possible. When I reached out to the Full Control Gcode guy(s) they said it could also work in a vase mode to eliminate the seam.

Examples are below if someone has questions about it and wants to work on it. Really should have gone to college or studied maths/programming better buuut...

You need a much denser pattern as you get close to any top surfaces.  To support these surfaces from within the part.  So the pattern needs to have a 3rd dimension.

What you describe sounds similar to the variable infill pattern which I think will hug the walls like in your diagram.  Until you get near a top surface.

Also the lightning infill I think might hug the walls a bit?

Right, it's about the pattern, not that specific image/design. Since the amount of infill between the walls can use existing infill patterns pretty much.

The 2nd example shows what a 3D design may look like. But a lighting infill example would look something like this, with 2 walls eliminating the outside seam, otherwise you can build up the bumps wherever needed to fully support a roof, just like lighting infill.
