About this 3D model
The 3mf contains the balls upside down since it looks quite nice printed in the textured sheet. It requires mmu and I have set it like so: 1. Orange 2. Red 3. White In order to make your print look like mine, I have printed the “light” reflection with white and the “shadow” with the same red the stars have. I have used sunlu orange pla+ since it is a little transparent when the layers are thin. Once layers stack up tranparency is gone. You'll have to test your filament to achieve the same result.
