On OS-X at least, read STEP/STP in to the free (open source) CAD Assistant (https://www.opencascade.com/content/cad-assistant) and use the floppy disk icon on left to save as ply (w/ colors) or obj (w/ mtl). Also check out the cool "Clipping plane" feature (bottom icon on left).
If you want to colorize first, use FreeCAD and http://sliptonic.com/freecad-hidden-gems-setting-colors-for-individual-faces/, save as STEP w/ color and follow instructions above.
All free & open source.
