A simple process art piece where a gestural line is drawn in Inkscape and extruded in OpenSCAD to create a 3D form. This cylindrical shape is then re-factored in MeshLab to make geometric vases. These were made for Chapter 9 in Practical 3D Printers http://www.apress.com/9781430243922.
Print in PLA with 0% infill and no top layers or modify the GCODE to leave the top open. Use PLA and 3 perimeters or 2 extra shells for a water tight bud vase. Then draw your own lines to make vases from.
