Here’s a detailed 3:1 planetary gearbox design, optimized for 3D printing.

Its compact structure and efficient design make it ideal for small-scale projects requiring increased torque.

Key Features:

1. Planetary Gear Mechanism:
   • 3:1 gear ratio provides torque multiplication while maintaining a small footprint.

   • The sun gear, planet gears, and ring gear work seamlessly to deliver smooth power transmission.

      

2. Compact Design:

   • Fits into tight spaces without compromising functionality, ideal for robotics, RC vehicles, or hobby applications (Ø70mm casing and 45,5mm length).

      

3. Durable PLA Build:

   • Designed to be printed in PLA, making it accessible, affordable, and easy to produce with common 3D printers.

     → Use more durable materials, if required by the application. 

     →Lubrication of the gears is beneficial!!!

      

4. Straightforward Assembly:

   • Simple, intuitive design ensures ease of assembly for both beginners and experienced makers.

     → All Parts just click-in place.
