This design features a pair of interacting bevel gears with integrated axle support, designed to transfer rotational motion at a 90° angle for compact drivetrain setups.

🧠 Design Features

  • Matched bevel gear pair for smooth power transfer between perpendicular shafts

  • Integrated axle mount for stable and precise rotation

  • Optimized tooth geometry for consistent meshing and reduced slipping

  • Compact design ideal for tight chassis layouts

  • Designed to work seamlessly with 3D printed RC drivetrains

🔄 Functionality

  • Converts rotation from the motor shaft to the drive axle

  • Allows efficient power transfer at right angles (90°)

  • Both gears rotate against each other while maintaining alignment through the axle supports

🖨 Print Details

  • Optimized for FDM 3D printing

  • Recommended:

    • 30–50% infill (gears need strength)

    • 3–4 walls

  • Print with high precision for best gear meshing

🔩 Assembly

  • Mount one gear to the motor shaft and the other to the axle

  • Ensure proper alignment so gears mesh smoothly

  • Use bearings or supports to keep the axle stable

  • Test rotation before applying load
