This model was designing in Fusion 360. Learn to design for 3D Printing by taking my online video courses at https://www.desktopmakes.com/
There are three stl files. A large at 170mm, a small at 120mm, and a solid model. The large and small are both designed to print with 0.8mm walls. Note if you scale these you will affect the wall thickness. If you want to try printing in vase mode then use the solid model, scale to size, and select vase mode in your slicer.
After printing I primed and spray painted the model with a textured sandstone paint which gave it a great look. Watch this video for post processing and design tutorial using Fusion 360. https://youtu.be/9wxzN8oqzz8
