Merge two shapes together into a wasp-waisted vase. Customize the number of sides, size, and shape of both halves of the vase along with the position and radius of the constriction point to develop a unique geometrical design.

Intended to be printed with zero infill and zero top layers (or, just stop your printer around 90%).

Part of my Customizable Containers series.

Printed the `double_taper.stl` sample in brown PLA on my Printrbot Simple with 0.15 mm layers, 11 bottom layers, and spiral vase mode (1 continuous wall and no top or infill).
