Inspired by the Einstein–Rosen Bridge (Wormhole) from general relativity, this minimalist optical illusion is made from just two flat pieces that slide together to create the illusion of a continuous curved spacetime tunnel.

Designed for fast, support-free printing, it's an eye-catching conversation piece for science enthusiasts, educators, and anyone who appreciates impossible geometry and optical illusions.

Features:

• 🚀 Fast and easy to print
• 🧩 Simple 2-piece press-fit assembly
• ✅ No supports required
• 🌀 Creates a striking wormhole / gravity well illusion
• 🧠 Great for STEM education, physics lovers, and desk decoration
• 🎁 A unique gift for fans of science, mathematics, and optical art

Print it in a contrasting color for the strongest visual effect, then view it from the front to reveal the full Einstein–Rosen Bridge illusion. It’s amazing how two simple flat parts can create the impression of curved spacetime!
