title: How to convert vtk to stl in python?
body: <p>I have around 500 vtk files that need to be converted to stl file. I usually use Paraview to convert them manually, but it takes forever. I wonder if there is a tool to convert vtk files into stl files in Python? I attached a screenshot of my VTK file.</p>
  
  <p>Thanks in advance.</p>
