Description

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

openscad.exe --export-format asciistl -o result\linear_extrude_ascii.stl examples\Basics\linear_extrude.scad 

openscad.exe --export-format binstl -o result\linear_extrude_binary.stl examples\Basics\linear_extrude.scad
