This allows scad files to be built in batch which will produce a preview .PNG and optionally a .OBJ and .STL output for each.
Tip Make sure the development version of Open Scad is installed as it has needed options for exporting.
Tip If first time set the source and destination directories.

The build is a single project that should build a 64 bit version and executable.
