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.
There are cubes you can print to help then understand volume or calculating. You can also create a lot of toy's and if they eat them it shouldn't be a problem becouse PLA plastic is made from plastic. (don't quote me on that, I am not responsable if anything does hapen)
