Here's another vase. It's spiky and twisty and a great conversationalist.
Shown here printed in Taulman 618 nylon. I can squeeze it as hard as I can and it doesn't break despite only being 2 perimeters thick. Plus it's shiny. Fun stuff!
I would scale up a little bit if you can. Wish I'd printed a bit bigger.
Print with zero infill and no top solid layers.
