Breastbone Free 3D Icon

This isometric 3D breastbone icon represents the sternum, a central bone in the human chest. It is useful for anatomy diagrams, medical education, healthcare platforms, biology lessons, and scientific presentations. Free to download, it adds clear visual support to educational and clinical content.

Every Breastbone detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is an isometric 3D render, on a transparent background, with no mask to draw.

It suits anatomy diagrams, medical education, healthcare platforms, biology lessons and scientific presentations.

Sizes on offer are 1024, 512, 256, 128, 64, 32, 24 and 16 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
