I learned how to extrude a revolve in fusion 360. this is my first go at doing this.
this vase is SCARY similar to ZYYX's vase. it is not a copy and their design came first. I designed this last week they designed theirs in 2015. crazy freaky how close they are. i printed both its "scary" how close they are and I free handed this design. universe is strange.
print in vase/spiral mode.
i personally print with a 1.2mm nozzle at 0.2mm layer height except the first 3 layers I do at .6mm layer height concentric spiral infill. then switch to vase mode at .2mm for a super clean finish but also super strong useful 1.2mm thick walls. (very tough)
you will need to seal the bottom to hold water at 1.2mm nozzle size. but at .4mm it should be easy to print water tight.
