Christmas Ornament Big Sphere / Half Sphere

Be aware that the printing parameters reflect for only a half sphere! I recommend not to print the whole thing at once to spare you the trouble of printing unnecessary supports and their removal of it. I recommend to print two half spheres and glue them together. I uploaded a proposal on how to slice it using as little supports as necessary. But feel free to tinker with it further. The model is designed in OpenSCAD.
