A set of lightweight geometrical christmas decoration balls 3DPrintd in Red, White and Black.

Why?

Because it was christmas and I wanted to design & make something with 3D Printing that was price competitive with mass produced objects.
Since 3D Printing costs are driven by volume and material used, I designed the geometry of these balls to use minimum material while keeping maximum strength, resulting in a $5 costs. quite OK compared with fancy mass produced christmas balls :)
