Chainmail by Zomboe

While Zomboe's thing uses square links on a square lattice, this one uses triangle links on a hexagonal lattice.
UPDATE June 6 2011 - At Zomboe's suggestion I chaged things so the vertical connections are trapezoids instead of small triangles. Hopefully this will make it easier to print. New Stls and OpenSCAD have been uploaded; the new files have "v2" in the filename.

Done! OpenSCAD has been modified with an adjustable "buffer" to add more material to the little triangles. New files are uploaded (they have v2 in the filename). A screenshot of the new version is also uploaded. :)
It prints! Very cool design, I really like the pattern that it makes.
Unfortunately, with my default settings the small triangles of the inner two layers are too small for skeinforge. I had to scale x and y by 140% before it would actually put any material there. Another option would be to lie to skeinforge and set perimeter width/thickness lower.

try replacing those triangles with parallelograms and increasing the unit size slightly to compensate.
My print didn't turn out so great so I definitely want to give it another shot when I get a chance.

I don't know if Skeinforge will repeat patterns on a hexagonal grid.
If you want to try stepping and repeating on a rectangular grid, you can try using the file "trimailRectangularUnitCell".
