This Earth Core Model is a layered 3D representation of Earth's internal structure, sliced open to reveal the crust, mantle, outer core, and inner core. Each layer is separated for easy printing, coloring, and assembly—perfect for classroom demonstrations, science fairs, or educational displays.

Designed with visual clarity and 3D printing in mind, this model can be printed in different colors or painted after printing to distinguish each layer of the planet. The cross-section is angled to allow clear viewing from the side, while maintaining a spherical silhouette when viewed from the front.

Features:

Includes crust, mantle, outer core, and inner core

Layers are separated and spaced for easy printing and painting

Designed for FDM printers, tested on Creality K1C

Makes science fun and tangible—great for STEM education

Scalable model: great for handheld display or larger builds

Tips:

Use color-coded filament or paint to highlight each layer

Print at lower layer heights for a smoother surface

Scale up for classroom-size demos

Use glue or connectors to keep layers aligned
