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 made a copy with a shell thickness of 5mm (2.5 on 50%).
The software doesn't allow me to add more but it should be enough.
Would be awesome if you could upload a picture of the finished print.
