This vase was formed by creating a a sphere with a hollowed out portion. That was repeated many times in a circular pattern. Then it was duplicated and shifted 12º so the circular portions nestled between each other. Then I duplicated the pair of rings three times vertically. To form the top and bottom I extruded with an 18º angle. The angle is negative for the top and positive for the bottom.
There are some thin/nearly horizontal points inside that technically do not work for a vase, but they are small enough that the print succeeds anyway.
It was printed using my spool rotator (https://www.thingiverse.com/thing:6114566) using Eryone tri-color co-extruded filament. The colors progress as a spiral around the vase - there is only one continuous stripe of each color.
