3D Printing and Revit STL Files

I recently got an email from a fellow Revit user asking if Revit 2014 changed anything for creating STL files, specifically if we could define inches as the base unit. I haven't had the opportunity to print anything to a 3D printer via a vendor myself yet so I'm clueless.

He shared with me his current frustration which apparently has to do with a fairly automated process that his vendors offer. Apparently it is as simple as: Submit your STL file online and get your automated quote in return. It works great as long as the submitted STL file uses the correct units, which is apparently "inches". If you don't cooperate with the system you end up having to call each vendor and it takes a lot more time than necessary.

He was specifically writing about the STL Exporter for Revit from Autodesk Labs. It exports to the units "Feet" and there is no way to alter that presumption. I've asked about it with a couple friends at Autodesk and it is on their radar so hopefully they can provide an option, in the future, for defining the units of the file output.

Since I have no wisdom to offer him and I know that at least a few readers have experience with this process I'm curious what alternatives he could consider. Can some other application that can edit STL files let him change the units? Perhaps the vendors could make this easier for customers and provide a pricing routine that asks for STL units? Is it more complicated than it seems? Comments are welcome!
