The one I printed for Sugardaddy was basic PLA, and that was about five years ago and it's still going strong. Now I mostly print with PLA+ which has slightly better fusing properties. But If you print slowly and with 100% infill, just about any filament will work. A 0.12mm layer height is the magic number for this design.Cool! I think it’s a beautiful designed bowl!
What ligament did you use to print it? I was slightly worried that soap might get between printed layers.
