The design of mechanical gears requires precise mathematical calculations involving module, pressure angle, and tooth profile to ensure proper meshing. Manual 3D modeling of gears is tedious and error-prone. This paper presents the development of a —a software tool that automates the creation of ready-to-print 3D gear models (Spur, Helical, and Herringbone) using parametric inputs. The system utilizes the Involute Curve equation to generate accurate tooth profiles and exports standard file formats (STL/STEP) for additive manufacturing. Validation through 3D printing shows that the generated gears exhibit a deviation of less than 0.1 mm from theoretical specifications.
