As we can see, 5 out of the last 6 months German manufacturing orders have fallen.

It is not, entirely, the really great thing it is made out to be. Most of the turbulence has been because of Trump. However I'm willing to bet that a large chunk is also to do with UK purchasing managers backing away from long term commitments with Germany when they don't know just how big a tax problem they may face going forward.
The UK is Germany's third largest export market. For the Germany, the UK does not make the top 10 of countries they import from....
More pain to go around and a large manufacturing base is not saving Germany from the pain.
