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.
You could easily do a 2-color print with it as it is! Just swap filament when it starts printing the numbers. I may add engraved versions if I get to it, but if you do a two-color print with engraved letters, one side of each piece will be a different color than the other. That could look super cool, but could also easily look really bad, especially if you didn't anticipate it.Edit: I've added engraved versions, thanks for the suggestion!
