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.
Most parts should be able to be 3D-printed at a lower scale. Nevertheless, some features won't be correctly sized. For instance, the spools will not fit the smaller holder adequately.
Our best advice is for you to keep the parts at 1:1 scale, but cut them into smaller pieces, print them, and then glue them together.
