Kid wardrobe space optimizer with linear bearings

I have a tall wardrobe on my 3y/o son room, which means that after hanguing his clothes, there is plenty of unused vertical space left. In order to optimize this, I recycled my old 3D printer into a running hanguing system, using the linear bearings and steel rods adapted with some designed 3D printed parts. 

You should be able to adapt this to any wardrobe just by changuing the steel rod lengths.
