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 water mold zoospore has an oval body marked with a large central nucleus and a scatter of rounded vacuoles. Two long trailing flagella curve behind it. A small knob joins the flagella to the cell at its narrow end. The smooth, simple shape shows the swimming spore stage of an oomycete clearly. Use it in a microbiology or botany lesson on plant pathogens, display it with other protist and cell models, or keep it as a clean teaching piece on a science shelf.
