The Munari is the first of the Montessori Mobiles, it can be used with children that are just a few weeks old (0-6 weeks), when they can only see high-contrast colors.

The Munari's time tested design with black and white geometrical patterns that helps the baby develop his ability to explore the world visually. It practices focus, concentration, tracking of a moving object and depth perception as the mobile moves gently on natural air currents and reflects the light

if you own a Bambu Labs X1/P1 or A1 you can simply load the presliced bed.

Otherwise you have to swap filaments mid print or paint them yourself by hand.
