Is there a middle ground here where error messages are displayed when an
invalid STL file is created, so that you can avoid feeding that STL to
your slicer while the other OpenSCAD features remain intact? Perhaps I
am missing a subtlety here

I do not receive emails while away from my desk,

If you know that I am on the road, please text me.
If you know that I am home, please email me.
