What are the common mistakes when export wall thickness 3D models?

Common mistakes when exporting wall thickness 3D models include inconsistent thickness across surfaces, using incompatible export formats, and not fixing non-manifold geometry. Inconsistent thickness leads to printing/machining errors, while unoptimized formats (e.g., STL) can lose thickness data. Non-manifold issues (overlapping faces) render models unusable in tools like 3D slicers. Before exporting, use Blender/MeshMixer to check thickness uniformity and test files in your target software to catch problems early.
