A set of cufflinks presenting the structure of a hydrogen atom. I got the inspiration for the design from the movie Watchmen. These are great for all Doctor Manhattan fans but the design is also very nice in its own right.
I have successfully printed this in polished nickel steel and it looks very good. The nickel color is quite similar to silver though the surface is rougher because of the printing process. Silver version has also been successfully manufactured and I think this would be optimal material for this design.
