My first idea came from bionics, also, I’m interested in golden spirals. I did some tests about deformation of curves since I’m inspired by nature texture, this artifact was printed by Ultimaker3, it needs very compact layer height can exert this smooth result. Also, I designed the shape of 3D model in Cinema4D, revolved the skeleton of the spiral. This is the reason why each single face looks different. It took nearly 50 hours to print it out.
The curve of this contour achieved the goal which I intended to. Surface looks like wave of liquid. Every sides are connected together smoothly.
Planetary is a gigantic topic, which means there are also the other sides worth of digging.
