Crafting items is only for keycards (and lightsabers if you are FS and have the skill and RMs for it). Its possible it will be used for other items later, but not currently.
There was talk, once upon a time, of using crafting kits, combined with creature corpses, to make basic-level items. E.g. a rancor tooth knife, nerf-hide workers coveralls, etc.
Hopefully something to that effect will start to be introduced once creature combat is all set up and there's a little breathing room to look at expanding the features.
