I've been working on Christmas ornaments, (see "Christmas Ornaments" and "Medallions for Christmas"), using openSCAD. "Buckyballs" could also serve as ornaments when hung from a string. Here are three more examples: Two are based on an actual holly leaf. A holly leaf was obtained from Trader Joe's and photographed. The photograph was converted to a path in Inkscape using the command "trace bitmap". Inkscape can output many file formats, one is file type pov for povray. The povray output for paths is very similar to openSCAD input for polygons. Povray uses < and > where openSCAD uses [ and ]. A block erase and two global changes in a text editor created a polygon command for the holly leaf. See the images at the left. Leaf_ornament.stl is the result of a number of experiments. It is a spherical shell with the holly leaf displayed at the center. Holly_leaf.scad creates it. Leaf_flat.stl came from commenting out most of holly_leaf.scad plus a few small adjustments. On completion of holly_leaf.scad it was obvious that the holly leaf could be replaced in the framework by another object. Snowman_ornament.stl is one such possibility. An image showing the two objects on the same platform is shown at the left. The module frame7a(), part of the openSCAD source files, can be used to create other ornaments. The ornaments are best constructed on a raft with external support and a level build platform. There is a tendency for the ornaments to pull free of the external support if the platform is not level. Note that the thickest external walls are aligned along the x axis of the platform. The software will construct the external support in that direction.
