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 single-celled Euglena modeled as a long, tapered spindle with its whip-like flagellum curling out from the front end. Rows of leaf-shaped chloroplasts wrap the body in a spiral, following the pellicle strips that give this protist its flexible skin. A rounded nucleus sits near the middle among small granules, and a recessed reservoir with an eyespot opens near the base of the flagellum. The graceful, swimming shape makes a striking microbiology display piece for a biology classroom, a pond-life collection or a science shelf.
