This is my tutorial that teaches you how to take your modeled, uvunwraped, textured weapon and put it into skyrim using just blender and nifskope.
I am using Blender 2.71 here.
You need the following:
blender: http://www.blender.org/
nifskope: http://niftools.sourceforge.net/wiki/NifSkope
FO3 Archive Utility: http://www.nexusmods.com/fallout3/mods/34/?
