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 sickle cell anemia capillary cutaway opens one side of a small blood vessel to show what happens inside. Round, dimpled red cells drift in at one end, then crowd into a jam of curved, crescent-shaped sickle cells that block the channel. The vessel wall is sculpted with flattened lining cells and their nuclei, and the outer surface has a rough, organic texture. It works well as a teaching model for a biology or health classroom and as a conversation piece on a science display shelf.
