Can I design or remix a model in SketchUp Make and legally share it via Thingiverse, MyMiniFactory or similar? SketchUp Make is licensed for non-commercial work only.  This includes the output from the software.  


  Trimble Navigation Limited and/or its affiliates ("Trimble") gives you
  a personal, worldwide, royalty-free, non-assignable and non-exclusive
  license to use the executable version of the Software for
  non-commercial use only. Non-commercial use means: you may not sell,
  rent, lease or lend the output of the Software or the Services.


The above retrieved 2016-02-07. The full SketchUp Make license can be found on the SketchUp website.  

In what ways does this restrict my use of SketchUp Make generated material with sites that allow the sharing of models (and deisgn files)?  This would include sites such as Thingiverse, MyMiniFactory and 3D Warehouse.  



For example, must I always set a non-commercial license for my designs? 
Thingiverse allows several different license choices to be selected.  

Can I permit the design to be printed by someone for money?
Thingiverse has links to 3D HUBS and Print a Thing which can be disabled per model.  

Obviously the SketchUp Pro license makes many of the restrictions on what can be done with the output go away, which would be much simpler.  However I do not expect to generate anywhere near the costs of purchasing a license ($695 US at the time of writing) by tweaking a few designs now and then.  



I want to comply with the licenses but I need to understand the limits of what I am permitted to do with SketchUp Make in order to do that.  It may be much more prudent for me to invest my time in learning other tools that have no restrictions on what can be done with the output.  

As this is a legal question it might matter what jurisdiction I am in and what jurisdiction the sites I may share to are in.  I am based in the UK.  Thingiverse is based in the State of New York.  MyMiniFactory uses the Laws of England as a base.  3D Warehouse selects the State of California.
Again, I'm not a specialist in intellectual property law (or any other sort of lawyer), but I have a different interpretation.

There is a potential difference between the use of the product, and the use of the derivatives of the product. For example, GCC has a restrictive (open) license, but its OK (in some contexts) to use the compiled code in a commercial product.

Generally, you (as creator of a work) will own all of the rights to a work. The supplier of the tools you use does not usually gain any rights to the resulting work.

So long as you don't gain from your use of the tool, it is probably OK for other people to profit from the use. Sharing with non-commercial should be your safest option if you're worried - but be aware that this doesn't prevent people from taking your design to a print service indirectly.

Their license says:


  Non-commercial use means that you may not sell, rent, or lease the
  output of the Software


This implies that they are not making any claims to restrict how other non-connected persons might use your works. Its specifically talking about use as part of employment, or you making a gain.

I would also note that to me the language in the license does not look to have been drafted with a clear understanding of intent on this issue.
