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.

Siege catapult with a long throwing arm ending in a shallow spoon cup, mounted on a four wheeled timber chassis. Two A frame uprights carry a rope lashed crossbeam, with diagonal braces, iron strapped joints and rivet studs along the heavy beams. A twisted rope and winch sit at the rear of the frame. The open wooden build shows every beam clearly, so it works well as a medieval siege engine on a battlefield tabletop, a castle assault diorama or a display shelf.
