Protein Crystal Free 3D Icon

A detailed isometric 3D protein crystal icon designed for biology, biochemistry, and laboratory visuals. Ideal for research presentations, educational content, medical science graphics, and molecular design projects. Free to download, this icon adds a clean scientific look to interfaces, posters, and study materials.

The Protein Crystal icon is an isometric 3D render with soft studio lighting, gentle shadows and a silhouette that stays readable from a hero section down to a 48-pixel UI slot. It ships as a transparent-background PNG, so it drops in without masking or background removal.

People put the Protein Crystal icon to work in biology, biochemistry, laboratory visuals, research presentations and educational content.

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.
