This vase is more rectangular in shape, something a little different in case the area you have is more of a square. I used a low poly look to the flat areas to give those areas more of an interesting, shimmering look.

It can be printed in vase mode or spiralize outer contour in cura, or printed in normal mode. You can uncheck spiralize outer contour, set top layers to 0, set infill to 0%. Bottom layers set to 3 or more. Set walls to 1 or 2 or more for a more sturdy vase if not in vase mode. Can be scaled to fit your needs. The vase in the photo shows vase not scaled at 100% of the stl file at 81mm wide for X and 72mm for Y and Z is 114mm tall. It has not been tested for being watertight and probably isn't printed in vase mode. If you make it, please post a photo, I'd like to see your print! Enjoy...
