We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

A herpes virus cutaway opening the round particle to show its nested layers. Clustered glycoprotein spikes cover the bumpy outer envelope, while the cut reveals a lumpy tegument layer packed beneath it. Inside sits a crisp icosahedral capsid with faceted edges, and at its heart a coiled, rope-like DNA core. Rich in surface texture and clear in structure, it makes a striking virology teaching model for a biology classroom, a medical desk or a microbe display shelf.
