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.

Ballista on two spoked wheels, a siege bolt thrower built around a long slider rail and a heavy cross beam. Twin bow arms are drawn back by a twisted rope bowstring, with knotted rope bindings at the torsion frame. A winch with cross-handled capstans sits at the rear of the rail, and a short prop post holds the rail level. Spoked wheels are joined by a straight axle under a curved carriage. Smooth rounded sculpting suits tabletop wargames, ancient battle dioramas and display shelves for anyone who wants a classic catapult-style war engine.
