How on earth can you assemble these ???

  

my “keys” are  threaded (with the same set of tap and dies, thank you Julien Mary who noticed that loophole) in the holes and at the end of the stems

 

If you want to make such a set yourself, you can contact me by clicking on the header “How on earth can you assemble these ???”

  1. Simple 🙂
    On the pic : Bottom left is (0,0),Top right is (1,1)
    – The threading is positive on diametrically opposed corners (0,0) and (1,1), positive means usual screwing way.
    – The treading is negative on corner (0,1) and (1,0).

    Then draw an axis between (0,0) and (1,1). Turning the plane containing our 4 points, along this axis in the positive way to screw the axis from (1,1) to (0,0), while pieces are in place, will screw them smoothly all together.
