A very quickly designed planter for Vase mode printing. I used a 0.6mm nozzle, 0.35mm layer height and a 1.45mm line width. If you want to riff on the design the Fusion 360 model is attached (please remember attribution if you do!)
Print however you please, Vase mode looks good though ;)
I suggest 5 layers for the bottom. Print the version with Triangular holes if needed - these holes work well to hold marbles to elevate the bottom of the planter in the tray. They are triangular to allow water to still drip through.
