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 haven't tried printing it yet (because sometimes the preview isn't exact) but I am also using 0.4 nozzle. Is there any way that I could finagle it to where I don't have to up size it? I am not capable in CAD software to widen the supports... :(
