Usage: Ideal for robotics and modeling applications requiring high torque transmission.
Design Features:
- Two gear ratios available: 37:1 and 49.3:1.
- Customization options by replacing sun gears.
- Designed to minimize backlash, enhancing performance.
Printing Recommendations:
- Print 3 or 4 planetary gears (4 recommended).
- For the 37:1 setup, use "Drive Sun 37:1" and "Driven Sun 37:1" parts.
- For the 49.3:1 setup, use "Drive Sun 51:1" and "Driven Sun 51:1" parts.
- It is advisable to print the NEMA 17 mount and an end cap for better gearbox functionality.
Ensure proper assembly of the planetary gears by following the provided instructions.
