This flower vase can be printed in spiral vase mode or spiralize outer contour in cura. Or, print in normal mode, uncheck spiralize outer contour, set... top layers to 0. Set infill to 0%. Bottom layers set to 3 or more. Set walls to1 or 2, or more, for a more sturdy vase. Can be scaled to fit your needs. The vase in the photo shows vase not scaled at 100% at 107mm wide and 165mm tall. It has not been tested for being watertight. It is for decorative purposes. If you make it, please post a photo, I'd like to see your print!

3d model print parameters
I use cura's, spiralize outer contour. Check your slicer's view, make sure you are printing a hollow vase with a bottom. The stl file is solid. Use 0 top layers, 0% infill if not printing in vase mode. I used a wall line width of .8, other widths might work, I haven't tried them. The print should take approximately 2 hours and 50 minutes using vase mode.
