The model in the photos was prepared with Bambu Studio and printed with Bambu Lab X1C.  I also included B. S. screenshots among the photos. Because I set the main body to 0.2 layer thickness and the star in the core to 0.12 layer thickness. 

The filament colors I use were chosen entirely according to my own taste and the materials I had on hand.   I know there are 3D hobbyists who have more fun than me. 

As a machine, I used a cheap product that works with standard AA batteries that are available in the market  ( 55 x 55 x 20 mm ).   A shaft length of around 13 - 15 mm is suitable.   I used the hour and minute hands by cutting the ones that came with the machine to length. 

That's all... 

Good luck...
