A visual educational and decorative model representing Einstein's General Relativity. The 3D grid demonstrates how mass curves the surrounding spacetime fabric. The front features the famous Einstein Field Equation in relief:

$$G_{\mu\nu} + \Lambda g_{\mu\nu} = \frac{8\pi G}{c^4} T_{\mu\nu}$$

Designed for easy filament switching or multi-color printing (AMS/MMU) to make the text pop. Perfect for classrooms, desks, or science enthusiasts!
