Used the included gcode - printed on my Ender 3 with zero issues. Broke free in seconds (just gently break it free by turning and feeling for the resistance), the raft came off without any issue (just be careful) and everything looks fantastic. Some little spots where it was over extruded, but that's no fault of the design itself. Painted the body/petals with a gold rattle can and the heart with some glossy red paint. Gold brought out imperfections, but it looks fantastic and I think my wife will like it.
Thank you so much FragrantAbyss for such an incredible design. A single print for something like this? It has blown everyone away that I've shown it to.
Print took about 7 hours.
