Aqui está a tradução técnica da descrição para inglês, que é o idioma padrão utilizado pela maioria das ferramentas de IA de modelagem 3D e softwares de engenharia: Detailed Description for 3D Model Generation (STL) - Subsoccer S7 1. Main Geometry and Dimensions: The STL model consists of a central, hollow rectangular bar. The external dimensions must be: Length (Height): 38 cm Width: 8 cm Thickness (Depth): 2 cm Style: The piece should have a smooth finish. It must be hollowed with a wall thickness of approximately 3 mm to balance structural integrity and material efficiency for 3D printing. 2. Hollow Side Sockets: On both narrow ends of the bar, the model must feature identical hollow rectangular compartments designed for a precision fit with plastic connectors. Internal Dimensions: Each compartment should have an internal width of approximately 1.8 cm and an internal height of 6 mm. Internal Detailing: Centered within the hollow compartment, include a cylindrical support pi
