As part of my efforts in continual, ongoing learning, I challenged myself to design a ring. I had an idea for a ring where negative space is used as a design element: diamond-shaped cutouts in the band itself. I also added embossed triangles surrounding the diamonds for more visual depth. When I realized this looked a bit like the markings of a diamondback rattlesnake, this ring named itself.
After a few sketches, I did some research to learn more about band profiles and shaping, and settled on designing a comfort-fit band.
Comfort-fit bands have a slightly domed inside profile, to soften the sharp edges of the band and make it more comfortable to wear. Since I wanted my design to work for both casual and daily wear, I chose to shape it for comfort from the beginning.
Turning a sketch into a 3D file
When I got my first draft of the 3D design done, I didn’t like the embossed triangles as much as I thought I would. Removing them was easy enough, and I think the band looks better with a simpler design.
The first draft also had a very thin band, which was below the minimum thickness recommended by several companies online. I added more material, although this made the diamond cut-outs look a bit thick and blocky. To reduce this, I cut a small offset step into each of the diamonds. This works as a subtle design element that reduces the visual weight of the diamonds.
Making prototypes
After making several rough prototypes on my own 3D printer, I used Shapeways for the first metal prototype. I selected 14k gold-plated brass so that it didn’t cost too much but still looked good.
Overall, I’m very happy with how the Diamondback Ring came out. I made a few small adjustments to increase the spacing between each diamond and therefore make the ring stronger.
Exploring production
I contacted a local casting company for feedback on my design, and they told me it could be difficult to cast. My design as it is has several places in it that would need filling sprues. I’m still working on the best way to improve the design, so it’s both visually pleasing and easy to manufacture. Setting up casting molds is an expensive process, so I’d like to only go through it once if possible.
