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 fallopian tube cross section shows the branching mucosal folds that fill its narrow lumen. Dense, coral-like folds twist and fork toward the center, ringed by a smooth band of muscular wall and an outer layer pitted with small vessels and pores. The flat cut face makes the layered structure easy to read and point at. It suits anatomy and reproductive biology lessons, a nursing or medical study desk, or a display shelf of organ and tissue models where students can trace each layer by hand.
