SEO Optimized Description

Create a sleek and protective 3D printable smartphone case featuring an integrated magnetic accessory ring, raised camera protection, and a matching free keychain.

This case is designed for makers, 3D printing enthusiasts, and small-scale manufacturers who want a modern protective phone accessory with a clean minimalist appearance. The raised camera area helps protect the camera module from direct contact with flat surfaces, while the integrated magnetic ring is designed for compatibility with magnetic charging and mounting accessories.

The included matching keychain uses the same visual design, making it a useful bonus accessory for personal projects, product bundles, and print collections.

The model is suitable for FDM 3D printing and can be customized, scaled appropriately for the intended device form factor, and produced in different colors and materials.
