I have some laser scans off of a ROMER arm of my cell phone and 2 tablets  (including a Nexus 7). They are saved in .IGS, .XYZ and .PSL formats.

How can I convert these into a .stl I can use for my RepRap?

I'd rather keep my few favors for the scanning and not the conversions in Polyworks or Reshaper.

I couldn't figure out how to get more than all the points in a line in Meshlab.

Suggestions?
