Determines the gear's size and gear ratio.

If your gears fit too tightly or bind together, adjust your slicer's "Horizontal Expansion" (Cura) or "XY Size Compensation" (PrusaSlicer) to roughly -0.05mm to shave off microscopic print artifacts. Troubleshooting Common 3D Printed Gear Issues Likely Cause Gears are binding/jamming Elephant's foot or insufficient backlash gear+generator+stl

offers spur, helical, and herringbone gears with a free online configuration tool. Set custom module, tooth count, width, and shaft type, then download ready-to-print files—designed to print without supports.

While many free tools focus solely on 3D printing, others provide crucial additional output formats for different manufacturing methods.

Increase this to at least 4 to 6 lines. You want the gear teeth to be entirely solid plastic, not filled with weak infill patterns. Layer 1 of 4000

: A free, dedicated designer for Spur , Helical , and Double Helical gears. It supports adding keyways, hex holes, or square holes for shafts.

When using a gear generator, you will face several technical terms. Changing these numbers alters the physical shape of your STL file.

: Focuses on spur gears with specific keyway support for secure shaft connections. Troubleshooting Common 3D Printed Gear Issues Likely Cause

Before diving into the tools, you must understand the key parameters that define a gear. Changing these values in a generator alters the geometry of the resulting STL file.

The gold standard for functional gears. Exceptional wear resistance and incredibly low friction, though difficult to print without an enclosed printer. If you are working on a specific design, let me know:

3D printers plastic tends to expand slightly. If your motor shaft is exactly 5mm, configure the gear's bore diameter to 5.2mm to ensure a proper fit.

: Built-in scripts like "SpurGear" that create native CAD geometry which you can save as an STL.

The wind had stopped.
