This simple bud vase listing includes 2 models, one with 2 holes that you can put string through to hang, and one without. I use this as a propagation jar.
3 walls with 0.4 nozzle, 0.2mm layer height. This has been enough with PLA+ to make it water tight.
No infill necessary.
Supports are optional (print slow) but to get smoother external wall on the overhang bottom, you can use supports. No supports needed in the internal.
This model is quickly printed and uses little filament.
