Upon checking the dowel centers for the Pen holder it looks like the 47mm parking post has dowel centers that are to far apart.
I measured the centers of the dowels for the 47mm parking post which are actually 55mm and the centers of the location circles for the passive pen holder which is 47mm.
So, at some time it looks like the 47mm tool holder got stretched to 55mm dowel centers.
