I'm wondering this as well. I was just about to print when I saw that it used the 0.2 nozzle (I only have 0.4). I don't want to waste 8 hours to find out that it looks like yours.
It wont print well on the 0.4mm nozzle, because its not precise enough. you can try to slice the file yourselg with the setting „detect thin walls“ If someone is dedicated enough they can optimize the models, by making the roses thicker
What scale is this of the original rose bear? I was going to attempt to print it with the heart accessory, so the scale would help greatly in sizing the heart
