Full color 3d printing in brilliant black and white! ;-) The dual extrusion counterpart to Julia Vase #002 - Flow. This version includes a vertex coloring texture based on the original fractal phase. I have updated and uploaded two versions: One for full color printers (PLY) One for dual extrusion printer (ZIP with separate STL files) Part of the Julia Vase collection: http://www.thingiverse.com/virtox/collections/julia-vase About 9.5 x 9.5 x 12.5cm, Wall thickness 3mm.The PLY version is for full color printers. It has smooth blending from white to black and vice versa. I don't suppose many have access to z-corp color printers at home, but their full color material is well suited for this version. That material is not very waterproof without coating, so suitable only for decorative and dry flowers.If needed you can convert the file to VRML using Meshlab. (Vert - Color should be ticked on save)You can get an optimized 2mm thick version in Full Color Sandstone here: http://i.materialise.com/gallery/julia-vase-002-yin-yangThe ZIP version is for dual extruder printers. It has sharp edges between the colors and contains four STL files:As I do not know how the dual extrusion 3d printer software wants it, I figure some combination should work :-)I uploaded the separate black and white files just for the cool renderengine on site. All needed STL's are in the zip.
