continuous inner walls to join hexagons for strength

As above, looking for a way to join all inner walls (if possible) in a hexagon shaped cutout, to eliminate or reduce strength losses from single line bonding. Have attached file of the project I'm working on (can't upload gcode for some reason).

 

Basically hoping to have long zigzags joining all the hexagons, instead of a bunch of hexagons nestled beside eachother.

 

Thoughts?

Good morning Daniel, 

Unfortunately the Forum is very picky about what files it will attach, 
and  it has an annoying habit of quietly dropping attachments that it does not like. 

the best way to overcome this, is to zip compress the files and attach the zip file. 

regards Joan

RE: continuous inner walls to join hexagons for strength

good morning, 
I am not aware of an option to achieve what you are looking for, 

there is an option to revise top and bottom layers which may add a little extra strength to the model 

single perimeters top and bottom, will cause solid infill, crossing the multiple perimeters surrounding the hexagons

The 3mf you posted has 100% infill except for the two attachment points.  

Afraid I'm not seeing the concern, maybe a few more words about what you think is an issue?

Do you think a diagonal infill pattern will increase strength?  I'm not so sure.  Much of the strength will come from the intralayer bonds, and forcing linear with perimeters is one way to maximize that bond; using an infill with a crossing pattern means a slightly smaller fused area layer to layer. 

To do what I think you are asking would be to reduce perimeters and top and bottom layers to 2 or 3 and select zig-zag infill at 90 or 100%. Though, something tells me that will be significantly weaker.
