Boron v1 3D files are all unusable

[SkyeFire]

None of the 3D model files for the Boron are usable. I've downloaded all of them, and attempted to open them in Fusion360, FreeCAD, and (for the STL) MeshMixer and Cura. Every attempt fails.

Fusion 360 throws an error for the STP and IGES files, and reports the .F3D file is "not a valid zip archive." No errors occur during the STL load, but nothing actually imports.

FreeCAD throws a generic "failed to load" message for the STP and IGES, as do MeshMixer and Cura for the STL.

Only the PNG file appears to be error-free.
