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.

Ringed in coiled helices, this bacteriorhodopsin model shows the light driven proton pump of archaea. It is arranged as a trimer of seven-helix bundles. Ribbon spirals loop around one another with connecting strands between them, and clusters of small beaded retinal and lipid groups nestle among the coils. Organic and smooth, it gives a cell biology or biochemistry class a tangible look at how microbes harvest light, and makes a sculptural molecular piece for a science shelf.
