I didn't get a usable print for multi-walled objects likes yours using the new spiralize feature. Cura seems to omit all other walls except a single one in the print and annoyingly does this for the bottom as well (make sure the shell thickness is about the nozzle size to get a solid bottom). It's hard to see even in the layer preview. A single wall might not be sufficient for a big vase like this (I'd use 3-5 perimeters on this one). My advise is to do a quick test print to check before starting anything big. Just my experience, ymmv, Denis
