This applies if your object rotates _exactly_ around that corner. In any
other case the following should work as long as the object is not too
complicated:

translate -0.50*(min_extent(myObject)+max_extent(myObject))

this actually centers the bounding box of the object but that should be
calculated correctly for a cube-ish structure

Hope this helps
