: These V-shaped gears provide the smoothness of helical gears but cancel out axial thrust. They are common in 3D printer extruders but must be meshed before mounting on shafts.
The size of the hole in the center for the shaft. Gear Thickness: How tall or wide the gear is. Best Practices for 3D Printing Gears
Larger fillets significantly increase tooth strength and prevent snapping. Choosing the Right Gear Type gear+generator+stl
Not the Generator’s light—it was still
Consider a small vertical-axis wind turbine built in a remote workshop. The designer: : These V-shaped gears provide the smoothness of
: Users can define the number of teeth, module (size), pressure angle, and bore diameter to ensure the gear fits their specific mechanism. Support for Multiple Gear Types
However, until all slicers support this, mastering the standalone remains the most reliable skill in a maker’s arsenal. Gear Thickness: How tall or wide the gear is
: Design two gears simultaneously to check their center distance and ratio.
Perhaps the most impressive among them is . This platform allows you to generate an incredible variety of gears, including spur, helical, bevel, herringbone (double helical), rack and pinion, and even internal ring gears. STLGears provides a wide range of customizable parameters, such as module, number of teeth, pressure angle, gear thickness, and mounting holes (including D-shaft, hex, and keyway cutouts).
Fusion 360 features a built-in spur gear script (under the "Tools" > "Add-ins" menu). For advanced setups, the community-created GF Gear Generator plugin allows for herringbone, bevel, and internal gears.
: Ideal for beginners, Tinkercad has a "Shape Generator" for basic gears that allows for quick adjustments to tooth count and diameter before exporting.
