Laser cut paper structures with generated supports

I've been working on various iterations of this program since my junior year of college. It's gone through some significant changes in that time.

Acrylic Triangles and edges. Horrible toxic solvent glue.

 

Acrylic Triangles and paired edges attached using cotter pins. Heavy wire support structure threaded through holes in connectors.


Coroplast Triangles and Acrylic snap-on edges.


And Now: Triangular card stock tiles with generated support structure

 

Process:

 

.OBJ files. Left is visualization of final geometry. Right is source


Generated .DXF (vector graphics format) file for laser cutting.
Red lines are cut, Blue lines are perforated for folding and white text is raster fill.

Result:

 

Folded tiles during assembly
Assembled object, supporting a subset of my library

  1. Could you explain the logic behind how you generated the connectors that only appear on the inside? I have been attempting this in Grasshopper but have been unsuccessful to get them only on the inside so far. Does your new version of LcAlg offer this ability?
    Thanks for your time.
