Three fluted vase 350MM tall

I included 3 options. A solid model so you can use “Vase mode” and set up how you like 0.4 MM thick walls 0.8 MM thick walls The last 2 have a 2mm thick bottom.

If you want to make it extra stout, use vase mode model, print with zero top layer, zero infill and as many walls as you want.
