I have an existing .stl model that prints well in every respect except overall size. I need the file resized to match the exact height and width I will supply once we start. Depth remains unchanged, so the geometry must be stretched or scaled only on the specified axes without introducing distortion or mesh errors. The finished deliverable should be a clean, watertight .stl ready for immediate slicing. Please use whichever CAD or mesh-editing tool you prefer—Fusion 360, Meshmixer, Blender, or similar—so long as the exported file passes basic integrity checks (no non-manifold edges, flipped normals, or intersecting faces). I’ll share the original file and the target measurements as soon as we begin; a quick turnaround would be ideal.
