Nova Right Arm Upgrade Elbow Forearm 6 DOF Hand with 3 DOF Wrist 3D print model

Upgrade Nova’s right arm with this premium STL pack, including a reinforced elbow, modular forearm, and a precision-engineered robotic hand with full wrist articulation.

The hand features 4 individually-actuated fingers and a 2-servo opposable thumb, giving it 6 degrees of freedom for highly adaptive grasping and gesture control. Combined with a 3-DOF wrist (pitch, yaw, roll), this assembly delivers fluid, lifelike motion for advanced interaction.

Built for performance and reliability — no tendons, no slop. Just pure servo-driven control.

Pack Includes:

Right elbow joint (servo-compatible)

Modular forearm shell with cable channels

6-DOF mechanical hand (4 linear-driven fingers + dual-servo thumb)

3-DOF wrist with full rotation control

Print-ready STLs for standard FDM 3D printers

Fully compatible with the Nova humanoid robot system (sold separately).Perfect for robotics developers, makers, and humanoid enthusiasts.
