NASA Fabric MK3 generator in OpenScad

This is a generator for custom NASA fabric (TurboDork version) in OpenSCAD.

Make sure the file NASA_FABRIC_Mk_3__Smooth2.stl is in the same folder as the generator.scad file

to design a custom fabric shape, modify the lists:

row_lengths = [3,4,5,6,5,4];
row_offset=[0,-1,-2,-3,-2,-1];

the names are pretty self explanatory, but I'll make it clear that the row_lengths determines how many 'rings' are there in a given row. The row_offset has to match the oddness of the number of a row, namely the the even rows have to have odd numbers and odd rows have to have even numbers:

right:
row_offset=[0, -3, -2, -5]
wrong:
row_offset=[0, -2, -3, -4]
but you will notice it when tinkering.

I added a low poly version of the hexagonal ring for the people struggling with performance.
