Part of the Julia Vase collection: http://www.thingiverse.com/virtox/collections/julia-vase This the dualstrusion cousin of the "Julia Vase #011 Heatwave". As with #004 Yin Yang, color is straight from the formula that also made the shape. In this case a cubic Julia with a spatial distortion filter. No dualstrusion? I have yet to try but I think in this case you could even print the separate parts and glue them together ;-) Do you like/print our designs?
