Great design. I scaled mine to 90 mm diameter and left the height of about 2.3 mm unchanged. However, the top layer is printing stringy, and the white isn't as defined as your photos. Do you have any suggestions? Should I print it thicker, slower last layer, face down? How many layers are you printing in total?

I like it very much, thank you. I don't have yellow and used orange (PLA Basic Bambu).
