Let's start from the beginning, with the 3D model. My main goal was to create a robot the size of a small dog, with easily replaceable parts and straightforward assembly. This meant using as few screws as possible. In the end, I believe I achieved these three objectives. Overall, assembling the robot requires only 36 screws (not including the screws provided in the servo kit). The leg offers three dimensions of movement with a reliable, rigid body. The robot consists of 21 parts: each leg has 8 parts, and the body is built from 3 parts (with an optional top cover extension). Each leg uses 3 servos. For more details on leg design, I recommend reading my previous post.

For the body, I designed just three parts to simplify assembly: the "Back Bumper," "Front Bumper," and "Body." Assembling these three parts requires only 8 M3x20mm screws.
