EasyPrint - Mounted ballista/heavy crossbow

Just a mountable ballista/heavy crossbow appropriately sized for a 25-28mm miniature. No supports needed! Re-scale for smaller minis. This ballista is strictly based in fantasy and has no historical equivalent. On a gaming grid, the ballista on its mount takes up roughly two squares constituting it (by d&d standards) as large sized. Would look good mounted on a ship. If you really want to mess with your players, place it in a long. 5 foot wide hallway. When the players open the door at the end of the hallway, let it loose!
