I've played a little bit with the pipe command in Fusion 360 and the result is a little set of vases (or perhaps containers for pencils, spoons etc.) that might be pleasing to you.
2021/08/01: A large but very low version has been added that we use to serve biscuits or sweets. BTW: Even if it's not a solid model, Prusa Slicer can slice it in vase mode. Combined with a 0.8mm nozzle you're saving a lot of material.
2020/11/18: Added some variations based on what https://www.prusaprinters.org/social/5-mikolas-zuza/prints showed in the Prusa Live Stream #13 (https://www.youtube.com/watch?v=Y0uSIv6BJRI&t=1789s)
If you like this little thing, you might want to check those ones, too:
