A refined version of vase1 by davvyk with less jagged edges and smoother surfaces, which was important because in the end I scaled it up to 175% of its original size.

I also added a version with drainage holes and a saucer with fitting shape.
The saucer is a closed volume, so it's meant to be printed without infill and top surface(s).
This has the advantage that you can choose the amount of walls yourself and you can even print it in vase mode.

EDIT: All models now have the proper sizes.
