Quadruped robot leg

🦿 Quadruped Robot Leg Design (MG996R / MG996S / MG9965 Compatible)

A modular, high-strength quadruped leg system designed for smooth gait control, durability under load, and easy integration with standard high-torque servos like the MG996R and MG996S. The design focuses on reducing play in joints while maintaining efficient movement for walking robots.

The leg includes a reinforced servo housing, a precision-aligned knee joint, and optimized geometry to balance strength and weight. All components are designed for easy assembly and repeatable performance across multiple legs in a quadruped setup.

🔧 Key Features

• Integrated servo mount designed specifically for MG996R / MG996S

• Reinforced screw channels for reduced flex and improved torque transfer

• Mechanical knee joint with smooth rotational movement

• Lightweight but reinforced structure for load-bearing stability

• Cable routing paths to prevent wire interference during motion

• Modular design for easy replication across 4 legs

• Optimized pivot alignment for stable walking gait

🧩 Assembly Instructions

• Connect both knee hinges together

• Connect the connector piece to both other prongs on each part of the leg

• Insert the servo into the dedicated hole(horns not required

🖨 3D Printing Instructions

• Material PLA or PETG

• Infill Percentage: 12% to 24%

• Wall Count: 3 to 6

• Supports Not required

• Print Orientation: Flat on ground prongs facing up

• Bed Adhesion Use brim if needed 

• Recommended Settings Notes: use strong infill because the MG996__ series servo's are powerful and could tear the filament.
