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've never had any trouble printing this model, including the front legs. In general, I have noticed that different slicers can handle the stl files quite differently, sometimes causing problems in specific cases. I have used Slic3r and Cura with success with these stl files. Otherwise, there could be some problem with the settings in your slicer. I've successfully used 0.3 mm layer height with 3 perimeters/shells. I have a nozzle size of 0.4mm. I do hope that anyone who has seen this problem and solved it can add a comment here.
