This is a simple and practical 3D-printed ear protector, designed for situations where the ear needs hard-shell protection — such as after ear surgery or when wearing newly-pierced earrings / cartilage piercings.

The protector works together with a 1 cm-wide elastic band, or any string you prefer.
Internal clearance is approximately 85 mm (length) × 45 mm (width).

The shape is intentionally kept flat and regular, so the design stays simple and is more comfortable when lying on a pillow.

I look forward to improving the design and creating variants for different needs.
