I wanted to make something for display. I started by creating a 3D model of a solid vase and ran it through something like https://www.voronator.com to make it more interesting. I then added a top rim and a bottom stand.

If you're able, print vase_an and vase_b in separate colors to make the ends stand out a little better.

as fine as you can go

The shell keeps integrity on this model really well. I expect that you won't need any infill for the vase. You will need infill for the base, however.

Print the model with as fine a layer height as you can for best quality.

Likely there will be some droop from individual layers where there is a lot of overhang. Post process these with a file.
