Gears 3D Printer is a small, free App that generates 3D models in STL format of spur and helical gears. The output STL file can be used with slicer software to print real plastic gears with a 3D printer or be imported with CAD or simulation software.
Simple and easy to use. No need for extra work, simply give the STL files to your slicer or simulation software and your gear is done ! This is the software you need to print gears.
