A Viking rubber duck, solid 3D model. Classic rounded duck body with smooth surface. Wearing a chunky Viking helmet with two short thick horns, sturdy and printable. A braided beard sculpted around the beak, exaggerated and bold. Small round shield strapped to one wing with simple embossed wood grain and a central boss. The other wing clenched like holding a tiny axe with a short, thick handle and wide blade. All details chunky, bold, and printable with clean geometry and no fragile thin parts.
