About this 3D model

(NEW UPDATE AVAILABLE) Improved part clearances for Bambu printers. Reduced force required for assembly. Gear design now clearly indicates the correct orientation for the shaft. Reduced backlash caused by tolerances. This is not a normal Planetary GearBox, but a Compound Planetary Gear which gives more ratio in a small space without stacking gears. Ideal for cranes and other applications with extreme torque, Self-locking , low Backlash , extreme precision, less load effect on electric motor, compact and compatible with LEG0technic. Ratio: 51:1 No hardware Required! Assembly Instructions ?️ Step 1: Obtain the part shown in the image. Step 2: Ensure the gear side is correctly oriented. The gear has only one side where the shaft can be inserted. Step 3: Add the remaining gears and make sure they are properly aligned. Step 4: Attach the cover with slight pressure. Enjoy and have fun :)
