I took a liking to a couple of vases from other creators and took a stab at my own design. It's something of an amalgam of my sources.
The pitchers pictured are scaled versions of the STL. The model is fairly resilient in the face of scaling.
Some of the pictured pitchers use an older STL model, where some of the wall angles were actually a bit too extreme. This has been resolved in the model available for download.
