Spiral vase for 3d printing.Designed for printing with a 0.4mm nozzle with a thickness of 1 wall. When printing, you must set the option - Printing in the spiral outline mode.Also added a model for printing in normal mode with an inner wall thickness of a few millimetersThe recommended layer thickness is 0.1 mm but I also printed 0.28 and it came out fine too.The file is presented in three formats, but I recommend using STL
