payment terminal 3d model

Create a small 3D printable exhibition giveaway shaped like a stylized self-service payment terminal. The object should be compact, modern, and visually recognizable as a payment terminal, with clean geometric shapes and smooth rounded edges. In the center of the front face, add a circular recessed cavity for an NFC tag. Cavity diameter: 25.3 mm. Cavity depth: 1.6 mm. Add small tolerance for easy fitting. The model must be sturdy, symmetrical, manifold, watertight, and optimized for FDM printing. Avoid tiny details, thin parts, text, logos, and unnecessary ornament.
