The 3D model features a flat-head wrench with a 12mm size, specifically designed for loosening screws. This intricate project involves the application of CAD (Computer-Aided Design) technologies and engineering principles to create a precise three-dimensional representation of the wrench. The flat-head design, coupled with the 12mm size, makes it a versatile tool for various applications, especially in screw fastening and loosening tasks. The project includes the development of a virtual prototype, allowing for in-depth analysis, testing, and optimization before moving to physical production. Through the integration of modern design tools, this 3D model exemplifies an innovative approach to tool design, employing advanced technologies to craft an efficient and effective product for screw-related tasks.
