Don't know if anyone else will find this useful but there is a free Destiny items STL generator.

The models it produces are raw mid-poly stuff, some work and some don't. I'm seeing reasonable results opening them in blender, adding materials to various surfaces and exporting as .fbx to import into Daz (and to be honest I have no idea what I'm doing).
If some kind skilful soul wanted to teach me how to UV and texture, or just demo it on one item that would be grand!
