Print in vase mode or spiralize outer contour. Or, uncheck spiralize outer contour, set top layers set to 0. Bottom layers set to 3 or more. Set walls... to 2 or more for a more sturdy vase. Can be scaled to fit your needs. Photo shows vase scaled to 110mm tall, 74mm wide. It has not been tested for being watertight. If you make it, please post a photo, I'd like to see your print!
Enjoy...
