WARNING: Model has issues if sliced in vase-mode. Model also has unsupported overhangs, that printed without supports.
This vase turned out pretty ugly in Black PLA, but I am posting it because I think the design is interesting in concept. The model was generated with custom code in python, imported into inkscape and converted to svg, imported into openscad then rendered into a vase shape. The model is an intersection of the julia fractal below, and its mirror image.
The Julia equation I used is in the following form:
z -> z^6 + 0.700 - 0.03*i
Iterations are limited by:
Re[z^2 + 0.7 - 0.03*i]^2 < 4
WARNING: Cura in vase-mode produces an unprintable mess for this model. It also has some unsupported sections, that printed without supports for me, but most likely need them.
