Valentine’s day a couple years ago I needed a gift and wanted to try making something myself. My idea was to use one generic cad model to create all of the pieces. While a well made parametric cad model is a thing of beauty not everyone want to receive one as a gift. So I had to actually make it. I like the way a hexagon gives a lot of freedom with shapes and contours; the same pattern could work for a ring, bracelet, and a necklace. The ring and the bracelet were straight forward to design but the necklace was much trickier as the ultimate bend profile was pretty funky.
I took the removal of cells to a bit of an extreme with the necklace, by fully removing cells. This also allows me to create direction in which the material will prefer to bend.
Thanks all, I used brass as I find it polishes up really easily and ends up with a nice color. I think I used a piece of pipe that was around as a form and then used a body work hammer and a block of wood to work it into shape. @goodkarmachicken I was lazy and just used the copper settings for the same thickness and then increased then just cut speed by using the coarse setting. Brass cuts a little easier than copper so this yielded a fine/medium results.
