9mm higher shelf so that 4 drawer and a basketdrawer under the hinge works. Not possible with orginal IKEA solution.
Thanks Dan ( @Dan_3D_49659 ) for this solution.
I made it only 9mm higher with cutting the model and extrude it.
The author remixed this model.
9mm higher for 4 normal drawer and a basket drawer on the lowest position is now possible.
If the shelf bend down, then there should enough space left between the shelf and the drawer.
