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.

Split down the middle, this kidney cross section reveals the renal pelvis and its branching calyces. Cone-shaped papillae and pyramids ring the central cavity. Renal columns separate the lobes, the cortex rim is finely stippled, and the ureter curves down from the hilum, with the adrenal gland crowning the top. Smooth, clear forms make each region easy to identify. With no base, it suits an anatomy classroom, a nursing student's desk or a medical display shelf.
