Personal Collection No.116, Difficulty: ⭐⭐⭐

Nautilus Dragon Spine. A very artistic bionic design; the spinning light and shadow are very beautiful; even when made in a single color, it produces excellent results. I couldn't resist this type of design, so I made it; single-color printing in metal or transparent colors works well.

For PETG printing, glue must be applied, otherwise there's a high chance of failure!
