This is just a simple assembly of ChaosCoreTech's master sword that can be found here:

I saw several people asking for a STL of the full sword assembled and I needed some practice in 123Design so I went ahead and assembled the parts and merged them all into a single assembled design.
The thing is nearly 1100mm tall - so the chances are you'll have to slice it up yourself to print, but this way folks with large z height can chop it up to their own preference.
