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 think they recently updated this.. last week, there were more files available (mask was split into 2 parts, plus some .thing files). Even now there are 2 different helmets (Rev 1 and Type 2). The Helmet Type 2 is split into 2 parts.. I think you either print the Rev 1 or Type 2 helmet, and print everything else.
