2. Render the Design: Press F6 to fully render the model.
3. Export STL: Navigate to File > Export > Export as STL to save your design as an STL file for 3D printing.

Parameter Descriptions

Module (Scale):
Defines the size of the gear teeth. A larger module creates bigger teeth and larger gears, calculated as the ratio of the pitch diameter to the number of teeth.

solar_teeth:
Specifies the number of teeth on the central sun gear. This influences the gear ratio and its interaction with the planet gears.

planet_teeth:
Sets the number of teeth on each planet gear, which mesh with both the sun gear and the ring gear.

number_of_planets:
Determines the number of planet gears in the system. More planet gears result in better load distribution and torque transfer.

width:
Defines the axial thickness of the gears, affecting their strength and stability under load.

pressure_angle:
The angle between the line of action and the tangent to the pitch circle at the point of contact. Smaller angles provide smoother motion but less strength, while larger angles enhance strength but increase friction.

helix_angle:
The angle of the helix in helical gears. Higher angles ensure smoother, quieter operation and better load-carrying capacity but generate more axial thrust.

clearance:
The space between the tip of one gear tooth and the base of the mating gear’s tooth. This prevents jamming and accommodates thermal expansion and manufacturing tolerances.

rim_width:
Specifies the thickness of the gear rim surrounding the teeth, ensuring structural integrity and resistance to deformation under load.

detail:
The resolution of the rendered gear. Higher values yield smoother curves and more precise models, though at the cost of increased computational load.
