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.
what slicer are you using, pretty much all slicers should be able to import .obj files. I would recommend using CURA, it can import obj (i use it for obj) and save them as gcode for your printer. otherwise you can also use blender to convert it to obj, just download the blender file i attached, open blender, click file -> open -> find the vase you downloaded as a blend -> click on it and ok -> once it is imported and you can see it go back to file -> click export -> select slt -> give name and bam you have yourself an stl. if you don't want to do that i can upload an stl file right now
