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
