Bowl and vases with openscad source file polygon generator.

pinshape

Open Scad file generates the entire solid with a skin of triangles. Stretch or shrink to get the size you want or pause part way to get a partial print. The clear and "blueberry" tall vases for example are z-scaled to 200mm high. Slices in mattercontrol, possible cura but not slic3r.  Note that most of these designs are from the thingiverse import feature which is missing about 30 of my designs and doesnt seem to update.  My current versions there are fully error free.  Do check back here though,  I have more to post!  :-)
