Christmas Ornaments

thingiverse

OpenSCAD allows for creating intricate spherical models, such as a hollow Christmas ornament made from a single line of code. The resulting STL file takes around an hour to print and produces a lightweight, smooth ornament. However, a 1mm thick wall can result in a slit on the sphere's surface. A slightly thicker wall is recommended for a complete sphere. The user also experimented with decorative patterns and holes on the spheres, using different commands in openSCAD. Sphere_holes.stl has star-shaped holes created using the difference command, while Sphere_star.stl features star-shaped images on its surface made through union and intersection commands. Both models require external support for printing and may have interesting support structures. The user encountered initial issues with spheres pulling away from supports but resolved them by leveling the build platform. Print times vary depending on wall thickness, with Sphere_star.stl taking around 90 minutes to print and Sphere_holes.stl taking slightly over two hours. Wall thickness can be adjusted in make_ornaments.scad. These spherical models are unique and fascinating due to their external support structures, making the printing process almost as interesting as the final product.
