Hello,
The Multimedia team at the Wikimedia Foundation is working to enable Commons support for 3D objects in the .STL file format.
While the technical work is well underway the Legal team at the foundation recently shared some points addressing 3D files from a legal perspective. Particularly concerns around patented objects and objects that are weapons.
I encourage Commonists interested in discussing the details of this feature to participate in a discussion in preparation for the feature. I have shared this on the Commons Village Pump if you would like to discuss further.
Yours,
Chris Koerner
