Here is example Python code to export fiber bundles to PLY. If you need STL you could change vtkPLYWriter to vtkSTLWriter, then need to comment the following two lines because STL doesn’t support colors (as far as I understand).

I’ve fixed the obvious syntax errors (due to VTK library upgrades) in the fiber tract export snippet. If you export generic models (not fiber tracts) then you can either export the whole scene as VRML or export a colored model to ply.
