My model did not pass the automatic checks for any of the steel options, I would have to thicken it. For reference, the price it estimated for steel options, (Stainless steel, matte gold steel, matte bronze steel, polished bronze steel, polished gold steel, polished nickel steel, matte black steel, polished grey steel) ranged from $9 to $14.
I haven't designed the clasping link yet. Apparently the new aluminum material (
