How it helps

Best practices

• - For meshing spur gears, gear pairs, and racks, use the same module and pressure angle.
• - Use 20 deg pressure angle and 17+ teeth to avoid undercutting on small involute gears.
• - For sprockets and timing pulleys, start from your chain or belt pitch, then test seating before load-bearing use.
• - Cut or print a small test piece first to confirm bore fit, backlash, kerf, and material behavior.

Limitations

• - Helical, bevel, worm, and other true 3D gear surfaces are not generated in this 2D DXF/SVG tool.
• - Kerf and backlash are single global values; planetary sets and spoke cutouts are 2D maker layouts, so test clearances before load-bearing use.
• - Internal ring, sprocket, and timing pulley profiles are practical 2D maker templates; verify fit before production parts.
