🔮 Trapped Sphere – Impossible Geometry Print

The Trapped Sphere is a classic impossible geometry design that showcases the unique capabilities of 3D printing. The inner sphere is fully enclosed within the outer shell and cannot be removed without destroying the model, yet it prints in place as a single assembly. This model is designed to print without post-assembly and demonstrates precise tolerances, making it a great conversation piece, desk ornament, or educational example of additive manufacturing. Ideal for showcasing printer accuracy, layer adhesion, and clean bridging. Prints best with good cooling and well-tuned retraction settings.
