Riikc created this piece using a 3Doodler pen and the 3Doodler STEM kit.
The joints in the hand are all movable, and the tissues and veins are all created using FLEXY plastic, which allows them to flex and bend. Likewise, different colors and materials were used to denote bone, cartilage, muscle, veins, arteries, and nerves.
The hand was featured on 3Doodler’s blog, including a full step-by-step guide on the creation of the piece.
