I thought it might break the vase, but it does not after pressing it in and removing it numerous times. ABS is somewhat flexible. I don't know how PLA would deal with the stress. PETg might be fine too.

Two different versions for your 3D printing pleasure, one straight and one twisted.
The models are completely solid and must be set up in your slicer to produce a vase. Do not print them solid! Use your slicer to generate a single layer side wall with 2 or 3 bottom layers and no top layer.
The one in the photo is is white ABS. 240/100C. No fan. No support. .38mm layers. About 1 hour 45 minutes scaled to 150mm high. You can scale to ach
