Affordable planetary gear sets, similar to what you would find in a drill?

I’ll be making some actuators for robotics and am having a hard time finding planetary gear sets I can integrate directly into the 3D printed actuator housings. [This]( ) looks like what I mean, but I’d like some more options and something with some more specs available. Does anyone have a source for this sort of thing? Thanks for reading!
