Scaling temporarily unavailable

File submission is paused for this tool.

You can inspect the scaled example and size report below. This tool cannot accept a model right now, including after sign-in.

What comes back

Scaled output + size report.

  1. 01
    Inspect

    Read the file-derived axis-aligned X, Y, and Z extents. STL values use the site's millimeter display/import convention because STL stores no unit.

  2. 02
    Convert

    Scale every coordinate uniformly about the file origin. Rotation is unchanged; offsets from the origin scale too.

    Receive the scaled output and a text report showing the before/after size.

Generated example · known box fixture

1 × 2 × 3 becomes 25.4 × 50.8 × 76.2 mm.

The service applied the explicit 25.4× option to the sample STL. The ZIP contains the scaled geometry and its before/after report.

The generated example remains available while file submission is paused. This fixture has no claimed physical size; verify your own model against a real measurement.

Verify the intended dimensions.

STL does not store a real-world unit. Use source documentation or a known physical dimension to calculate the factor, then check every fit-critical dimension and tolerance before printing.
