This design features a pair of 3D printable bevel gears with open axle bores, allowing direct insertion of a motor shaft or wheel axle for flexible drivetrain integration.

🧠 Design Features

• Matched bevel gear pair for smooth 90° power transfer

• Open center bore on each gear for easy mounting onto:

  • motor output shafts

  • wheel axles

• Secure fit designed for press-fit or set screw attachment

• Optimized for consistent meshing and reliable rotation

• Compact and adaptable for custom RC and robotics builds

🔄 Functionality

• Transfers rotational motion between perpendicular shafts (90°)

• Enables direct connection between motor and axle without extra adapters

• Designed for smooth engagement when properly aligned

🖨 Print Details

• Optimized for FDM 3D printing

• Recommended:

  • 30–50% infill

  • 3–4 walls

• Print with high precision for best gear performance

🔩 Assembly

• Insert motor shaft or axle into the gear bore

• Secure using press-fit, adhesive, or set screw (if added)

• Align both gears carefully for smooth meshing

• Test rotation before applying load
