I liked this up, The big question is at what level are you going to design this. Are you going to simply specify the gears to of the Boston Gear catalog or perhaps you need to know how to generate the involute curve for the internal gear or maybe find the loads in the carriers.
Most people will try and use stock parts even if they plan to 3d print the parts in plastic -- The reason to use stock parts even for printing is because Boston Gear has CAD files for every one of their stock parts. You would not have to design the gears. (This makes it passable to use helical gears) Designing from requirements and bare metal is not something even a professional is going to do in just a few hours Looking at these in some detail, there are a lot of parameters to select. For example it looks like all 8 planet gears on this have the same number of teeth but that need not be the case. And then some designs used helical gears, they say to do that if the tangential velocities go over 25 M/s. These designs have to be done trail and error, interiorly because obviously the number of teeth must be an exact integer another are only a limited number of stock parts in any one catalog.
