A wave vase i created with Fusion 360. Print in Spiralize mode with no top. Mine was printed in 0.2 layers with 0.6mm layers at 30mm/s on an Ultimaker 2 Extended There are two STLs, the one I printed is WaveVase_200mm.stl (the other one is the original design i made, i rescaled it in Cura to make it taller).
