• Spur Gear — Straight-cut teeth for simple power transmission
• Helical Gear — Angled teeth for smoother, quieter operation
• Herringbone Gear — Double helical for zero axial thrust
• Bevel Gear — Conical gears for perpendicular shaft connections
• Worm Gear — High reduction ratio worm and wheel pairs

• 13 standard module sizes: 0.5, 0.8, 1.0, 1.25, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0, 8.0, 10.0 mm
• 3 standard pressure angles: 14.5, 20, 25 degrees
• Customizable tooth count, face width, and helix angle

• Export watertight manifold STL files — no repair needed
• Tested and verified on Bambu Lab printers
• Proper bore holes for shaft mounting

• Real-time 3D visualization powered by Three.js
• Orbit, zoom, and pan controls
• Meshing gear pair animation
• Dimension readout panel with all gear specifications

• Works on Windows, macOS, and Linux
• Fully responsive on Android and iOS devices
• No install, no signup — just open and design
