2025 Update
Alright so I changed the mesh for a more streamlined geometry.
Filament used in the new version:  eSUN PLA-Silk Magic (Blue+Orange+Green)
Important: Make sure It's the 2025 printer profile before printing.

Changed the profile, removed the extra bottom layers if you want it filled with water read further down.

Changed layer height from 0.1 to 0.12.

I'm proud to present you my latest vase which i spent the last couple of days with! 
I've had a blast creating this and printing, got a late night delivery of some new filament from esun more specifically "eSUN eSilk-PLA Magic Gold+Green+Black", Last 2 photos the filament used is “eSUN eSilk-PLA Magic Blue-Green”

Will it hold water?

It's possible but not just using the profiles here, you have to manually find the right flow/nozzle temp and right a month of bottom layers for your filament.

But… There is a better way, you can seal the bottom with wood glue, make sure it gets into the corners too and let it dry can take up to 48 hrs for the corners to get dry. (Get the right kind of glue, here in Sweden It's marked as outdoor that one is water resistant)

Printed info
Created in Blender.
Printed with Bambu lab X1C, 0.4mm nozzle, 0.6mm line width, 0.1mm line height, vase mode.

~208mm tall, 4-5 hrs print time,

Some notes:
It's possible to print this in other settings than the profile i have however for optimal quality i highly recommend 0.1 layer height.
There's also an ultra poly version(Download raw model, non wide version), honestly don't know how much of a difference it makes printing but why not include it as well.

Enjoy!
