Before you print: This first version is a 2.5D print-in-place converter: it preserves the top silhouette and contour but fills undercuts, gaps and underside cavities. Best for elongated models lying along X. It does not guarantee any arbitrary 3D model is printable. Always check model dimensions, sliced layers and physical fit; watertight geometry does not prove mechanical performance.
