I wanted to say that I have entered this instructable into the jewellery contest, I would love to win a 3d printer, and have been trying to save for one for what feels like ages now,and being 15 years old i'm struggling :/
A history of the Idea
The idea to make these cufflnks came when my dad brought home a highlife magazine from an airport with a picture of the square mechanical tateossian cufflinks, saying that that was what he wanted for fathers day, half joking as they cost £70 ($106).
Being broke I set out to make them, orrigionally I made them out of steel box section, but they were very heavy and too big. I went back to the drawing board. When I did some more research, I found that Tateossian also made circular versions of the cufflinks, I mch preffered the shape of these cufflinks, but preffered the look of the cogs on the square ones, So I decided to make a cross between the two.
