Tim Allison commented on TIKA-4223:
-----------------------------------
So, the one microsoft stl that I can find online:
http://ctldl.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab
is the wrapper. The stl file is actually a {{application/pkcs7-signature}}.
Further, when I google or duckduckgo "stl" and file format, the answer is far
and away this shape format, not the vnd.ms-pki.stl.
So, I propose, moving the glob for ".stl" from vnd.ms-pki.stl to
{{model/x.stl-binary}}.

> Project: Tika
> Issue Type: Improvement
> Affects Versions: 2.9.1
> Reporter: Robin Schimpf
> Priority: Major
> Attachments: linear_extrude_ascii.stl, linear_extrude_binary.stl
>
>
> STL files can be in ASCII or in binary format. Exporting this file
> ([https://github.com/openscad/openscad/blob/master/examples/Basics/linear_extrude.scad)]
> with OpenSCAD into STL the ASCII result file is detected as text/plain.
> Also the binary STL is detected with application/vnd.ms-pki.stl which differs
> from the model/stl mime-type Wikipedia lists for those files.
>
> Used commands for attached files
> {code:java}
> openscad.exe --export-format asciistl -o result\linear_extrude_ascii.stl
