This card tracks a proposal that's currently part of the Community Wishlist Survey: https://meta.wikimedia.org/wiki/2015_Community_Wishlist_Survey
The Wishlist Survey voting phase lasts until Dec 14th. After the voting has concluded, the top proposals will form the backlog for the Community Tech team to investigate and address.
See also T3790: Allow uploading of 3D files to Wikimedia Commons, which may overlap/duplicate.
It would be nice if Wikimedia develops its infrastructures to be able to host free 3d works, just like what Github and even thepiratebay! did while ago. Image thumbnail of a 3D model can be used on content articles also, just like PDF files and video clips. Wikimedia foundation should keep itself relevant on new ways and new interests of FOSS communities. Fortunately it is currently filed as a bug, phab:T3790 but not progressed much.
