3D Printable Teddy Bear Charm

I’m creating 2 small teddy-bear charms and 1 small dog charm that will ultimately be cast in metal, and I need a clean, watertight 3D model that’s ready for printing. You’ll receive my reference photos at the outset; they show the pose, proportion, and the subtle “cuddly” feel I’d like to capture...
