I drew this vase by hand on a sheet of paper, then placed a few dots at critical points on curves (see image). I measured and marked the coordinates of each dot in mm (lower left corner was origin). Using 123d software and the "spline" draw tool, I recreated the curves on a 100mm by 125mm by 36mm "box."

This was printed on a MakerBot Replicator, then I added quarters in the bottom opening to weight the vase so that it would stand.

The file, "vase deep hole.stl" holds 16 quarters and will allow larger flowers on the right side.
