stone fort wall 3d model

Create a 3D model of one straight stone fort wall with no towers, no gates, and no terrain. Wall length: 50 cm Wall height: 10 cm Wall thickness: 1.5 cm Design it in the historic Maratha fort style, like Raigad Fort, with stone-block construction and battlements (crenellations) along the top edge. Keep both ends flat and open — no corner towers. The model must be solid, watertight, flat-bottomed, and ready for 3D printing (STL format). Include slight stone texture for realism, but no other structures or decorations. no tower at end just wall
