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 added an STL of just the leaf (leaf4.stl). You'll need to print it with a brim to keep it standing up. Also, I'm not sure how easy it'll be to get it assembled into place if printed separately.
