STLMESH · PROFESSIONAL BROWSER TOOL
Look closer at your STL mesh.
Detect binary or ASCII STL, calculate triangles, unique vertices, area, bounds, and signed volume, then use undirected-edge incidence to find degenerate facets, boundary edges, non-manifold edges, and same-direction joins.

Stores only the visible result summary, time, and an optional short label; imported files and input controls are never stored. Imports must match this tool and stay under 128KB; comparison also stays on this device.
02 · CAPABILITIES
Built deeply for one narrow workflow
Area, volume, and bounding box
Boundary and non-manifold topology audit
Edge incidence cannot detect every self-intersection, thin wall, normal semantic issue, unit, slicer constraint, or printer limit. Passing a basic topology audit does not prove printability, dimensional correctness, or mechanical safety.
