Select STL (Binary) as your export format. Binary files are smaller and faster to process than STL (ASCII). Optimizing Gear STLs for 3D Printing
Not the Generator’s light—it was still
A free, versatile online designer that can generate spur, helical, herringbone (double helical), and internal gears. gear+generator+stl
A flexible parametric tool that lets you adjust the "roundness" and width of teeth in real-time. 2. CAD Software Add-ins STLGears.com | The Free Gear Designer
focuses on spur gears with a clean, intuitive interface. Adjust tooth count, pressure angle (20° for metric, 14.5° for imperial), and module, then export to STL, SVG, or DXF. Keyway support helps secure gears onto shafts. Select STL (Binary) as your export format
The Ultimate Guide to Using a Gear Generator for STL 3D Printing
: If the generator doesn't output an STL directly, you might download an SVG to import into software like Fusion 360 for final adjustments, such as adding a shaft hole. : Save the final model as an A flexible parametric tool that lets you adjust
Determine your required gear ratio (e.g., a 10-tooth pinion driving a 40-tooth gear creates a 4:1 reduction).
