4-pin fan header

I'm using some spare fan extension cables for a project and wanted a way to connect them to a PCB to guarantee correct orientation. These are 0.1" headers.

If you've built a PC, you should recognize the 4-pin fan connector because of the tab sticking up on one side.

### Assembly instructions for Fan Header Male:
> Take 4 loose square header pins and shove them through the 3d printed part. Be careful not to bend the pins or stab yourself. This is a very tight fit so it will take some work
