It's only a sword!!! - 3D printable version
This model is a 3D printable version of ImPanic's "It's only a sword !!!" (It can be found here: http://www.thingiverse.com/thing:488868)
I took his version of a blender model shell and exported it to a format that Sculptris could read. This made it into a 3d object instead of just the shell. (This is the downloadable obj file)
From there it went into 3D Builder in order to split it in half to provide flat surfaces for printing. (This is the downloadable stl file)
The two sides glue together well but you will need to mess with the scale for your purposes. I believe LEGO sized is around 120%. ymmv :)
