MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I've had a go at making a similar thing using OpenSCAD here, its not quite finished and the text was a nightmare (e.g. no multiline support in OpenSCAD). I was going to try to just remove the text from the STL but OpenSCAD didn't like difference()'ing with it, seems its quite common from Rhino output.
