Spur Gears

This pack contains simple, clean spur gear models designed for general mechanical use, prototyping, testing, and educational projects. These gears are optimized for easy FDM printing and are suitable for hobby robotics, mechanisms, and calibration experiments. All gears are modeled with consistent tooth profiles and accurate spacing to ensure smooth meshing when printed at standard tolerances. The models are solid, support free, and designed to print reliably on most modern printers.
