The planetary gearbox is designed to fabricate it by using the 3D printer or using a CNC machine, all details you can find in the design files, you can use it for several projects [Robotics, lifting mechanisms,...], you can increase the torque of your motor, also you can assemble multiple stages to get higher reduction ratio.
Design Consideration The gear module is 1.5M, the Ring gear has 60 teeth, the Sun gear has 16 teeth, and the planet gear has 22 Teeth. all assembly of gearbox designed to achieve reduction ratio 1:5
The fabrication you can fabricate the planetary gearbox by 2 ways
3D Printer: you can find all STL files required for a 3D printer CNC Machine: also you can find the g.code files inside the manufacturing folder.
NOTE The maximum allowable Torque for the gearbox depends on the material you use it in fabrication**
