3d printable cup holder

A functional 3D-printable cup holder designed for everyday use. The cup holder is cylindrical with a flat base and thick walls. Inside the cup holder are three evenly spaced vertical protrusions extending inward from the inner wall, creating three internal grip sections that allow different-sized cups to fit securely. The protrusions are rounded and slightly flexible in appearance, not sharp. The interior is smooth and tapered slightly toward the bottom for stability. On the exterior of the cup holder, include a strong clip attachment designed to snap onto edges such as a desk, stroller bar, or chair arm. The clip is integrated into the body, has a spring-style curved shape, and is thick enough for FDM 3D printing. The model is solid, watertight, has no overhangs steeper than 45 degrees, and is optimized for STL export and 3D printing
