I got the Ikea Vesken version with 4 bins but wanted 2 towers of 2 bins out of this.
So i remade the top plugs and bottom legs.
The fit is quite close so you have to push them in a little, no idea if they will ever come apart easy. But they will be together for sure.
this includes the top clip and bottom legs to make it one sturdy overall piece.
The author marked this model as their own original creation.
