To make parts more waterproof we recommend that you increase the number of perimeters of the part (3, 4, 5 shells or more) and also increase the filling (30, 50 or even 100% infill in your part). Read on for material, slicer setting, and post-processing tips! In this case, the monkey mesh exists of three separate parts, featuring open edges: the head and two eyes. Thus, in case the 3D design contains non-manifold modeling errors that prevent this precision of geometry, the 3D file will not be recognized by the 3D printer, and consequently, the 3D model will not be printed. The model just needs to be a watertight closed volume called a SketchUp Solid. Go to Cura 3.1 and select Print Setup >> Custom >> Special Modes >> Spiralize to enable Vase Mode.
