solve title by genius42.

credit for this solve goes to jammuu, who drew up this layout on paper while she was on a boat and didn't have access to a computer. at first i kept running into trouble with the triarm grabbing things it wasn't supposed to. then i had the idea to rotate the hexarm backwards to output the tin and silver, which made the whole thing work. surprisingly i spent longer on this than on instructions. hope it was worth it.
