This many faceted vase based on septagons.  It incorporates many twisting planes that flow upward until the top where the facets disappear into a rounded top.

It was printed using my spool rotator (https://www.printables.com/model/523118-spool-rotator) using Amolen tri-color co-extruded filament.  The colors progress as a spiral around the vase - there is only one continuous stripe of each color.
