Domed Round Knot Ring
- Modeled in Rhino with knot from Knots3D
- machined with rotary axis replacing the mill's Y axis
- investment cast
- dome in centre fabricated in silver
- prepolished and assembled

Model
- Rhino model showing domed centre which was fabricated in silver for the actual ring
- the knot was created with Knots3D
- with the knot's basic geometry being used for reconstruction in Rhino, simplifying its manipulation. Here the knot does have depth, but only really needed for making a nice rendering.
- Once the model was finished surface meshes were generated and these were 'unrolled' for machining with a rotary axis replacing Y

Model variation
- re-using the knot and its modifications with a new shank
- CAD/CAM makes it almost too easy to try to perfect a design. Not only nice visualization tools to use before starting but I can be milling the improved variation while finishing the first itteration.
