The original Blender/OBJ package was downloaded directly from the author's site.
No login or paid-download restriction was bypassed.

Local derivative: intellimouse-optical-usb.glb
Converted from the original Blender 2.79 source using Blender 4.5 in background
mode with --disable-autoexec. No attached scripts were executed. The original
source files remain unchanged. No new model geometry and no decimation.
The author's existing modifiers were evaluated for glTF export. The source and
export each contain 11,420 triangles. The empty curve profile helper has no
renderable triangles and is omitted by the exporter.

Material compatibility changes only:
- Original diffuse colors mapped to zero-specular nonmetal glTF materials.
- Original 512x128 HDR logo mask re-encoded as PNG alpha with the same UVs.
- Original plastic colors and existing Principled material values preserved.
- Original 50/50 Glass/Emission tail material approximated with glTF transmission
  and half-strength original emission. Arbitrary Blender shader mixes are not
  represented exactly by glTF.
The converted model and these adaptation contributions remain CC BY-SA 4.0.

Limitations: This is an independent old Microsoft mouse asset, not manufacturer
CAD. The author says color is calibrated but roughness/specularity were guessed.
It has no modern PBR normal/roughness texture set; its only texture is the logo.
The original geometry includes only a short cable stub. It is a compact retro
mouse with modeled shell seams, wheel, side controls and red tail material.
The package thumbnail is the author's preview. intellimouse-glb-preview.png is
a new inspection render of the exported GLB; its neutral ground/lights are not
part of the exported asset.
