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.
Print the drawers with the handles on the ground plane. Supports should not be required to print the drawers since there are no complex or hanging features. The shelf may need supports though.
Edit: do not print as oriented, my CAD program is saving stl files on the wrong axis
