Knot Band Ring
- Modeled in Knots3D and Rhino
- machined in wax with rotary axis replacing the mill's Y axis
- finger hole bored on lathe
- investment cast
- oxidizied and polished

Model (for milling purposes only)
- The knot was created in Knots3D and modeled with a triangular cross section
- After importing the mesh to Rhino one face of the triangle was extracted
- This planar knot is suspended over a surface (which will be inside of shank) and the tool path generated for a rotary axis milling
- With carefull attention to the model's end geometry and milling parameters the knot becomes endless
- (I am exploiting the fact that the mill can't cut undercuts to GREATLY simplify the model)

Model (fancy render version)
- Here the milling model has been used to create a 'solid' version for visualization
- depth is added to flat working model
- ring shape created by rolling surface meshes of finished working model (the small gap being left at 'seam' is closed before generating milling toolpaths)
