Well... on our testwikis.

We still have to work out a few details before enabling 3D support on Commons, but this is a major step towards getting there.

Mark just[1] uploaded[2] the 2 first STL files to these testwikis.
Please help us test and file a bug[3] if you experience issues.

Thanks to everyone involved in making this work!

Matthias
