Bathtub U-Boat - 2014 Edition
This derivative of the original Bathtube U-Boat has been cleaned up tested with the current generation of slicing tools. Skinforge was primitive and slow, but it would slice anything eventually. MakerWare and Slic3r are much more efficient, but can't readily cope with the geometric errors present in many older models
The clean-up was done using Netfabb Basic and the SketchUp plug-ins SolidInspector and CleanUp.
