STL → OpenSCAD File Converter

In OpenSCAD you can use import(example.stl) to import an STL. However, Thingiverse Customizer doesn't support the import command, and it requires that everything resides in one .scad file. With this tool, you can convert all your STLs to OpenSCAD modules, copy and paste each module into one big SCAD file, and call the module instead of using import().
This is how I created the 3DVerkstan Faceshield Stacker Customizer.
