Sketch to "drill" the hole for the bolts

To take away the material for machining the inside of the holder, very conveniently we can use the Skeleton Body itself. If you don't want that because then the skeleton gets hidden somewhere deep in the tree, you can also duplicate the sketch of the skeleton Revolution feature and re-create the revolution in another body. This is not completely parametric, though, because the duplicated sketch is independent of the original, so you will have to work on both if you change a dimension. Dependent duplicated features might be supported in the future sometime.
