Shimano 3S hub
I have a rear wheel that has a Shimano 3S hub on it and I want to save the parts from the hub in case I can use them on another bike, but can't seeem to get it totally disassembled. I got all the pieces out except one I think. I'm not sure what it is called, I think it is the gear assembly. It spins but doesn't want to come out. It will slide back and forth but just not far enough and I don't want to force it. Here is a picture of the part.

Broke an axle in one of these once. Haven't ever needed to delve any further.
Ran em on this.
Doubt you'll need the spares.

I wrote the entry below before looking more closely at your pic. There are several odd things about it. I see no spoke holes or even a clear hub shell, and the ball cup is not oriented in a way that would allow the hub to be driven (seems reversed 180 degrees). I thought this was a 333 hub but now I'm not so sure.
The part that needs to come out 1st is called a ball cup (circled below) and you have already made it impossible to remove, by detaching the hub from the rest of the wheel. A tool called a ball cup remover is used that is similar to a freewheel remover, and you MUST be able to hold onto the rim of a built wheel to exert enough leverage. There is no way to hold onto the hub while turning the tool otherwise. Further, it should be obvious that you will not be able to remove the part that is moving without removing the ball cup. You need to be very careful in the future about diving into disassembly if this is a typical example. Finally, even if you had been able to disassemble, the odds of you coming across another hub of this type that needs a part you have is miniscule. It's only good now as a paperweight.
