Torus.3mf forms bad .zip

[BenjimanWhite]

unzip reports these errors:

unzip -t torus.3mf.zip
Archive: torus.3mf.zip
warning [torus.3mf.zip]: zipfile claims to be last disk of a multi-part archive;
attempting to process anyway, assuming all parts have been concatenated
together in order. Expect "errors" and warnings...true multi-part support
doesn't exist yet (coming soon).
error [torus.3mf.zip]: missing 8589913447 bytes in zipfile
(attempting to process anyway)
error [torus.3mf.zip]: attempt to seek before beginning of zipfile
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

Also tried with both tar and Archive Utility, and both are unable to unzip.

@BenjimanWhite I see that this file unzips just fine: https://github.com/3MFConsortium/3mf-samples/blob/master/examples/core/torus.3mf

littlebook:Downloads snwright$ unzip torus.3mf.zip Archive: torus.3mf.zip inflating: _rels/.rels inflating: 3D/3dmodel.model inflating: [Content_Types].xml littlebook:Downloads snwright$

Can you confirm on your end?
