IKEA BROR Shelf Elevator

For everyone with a BROR shelf from IKEA who is struggling with a given height of their shelves. In my case, I could not open the AMS on my P1S due to the installed LED Riser from make 3D which increases the height of the AMS sitting on top by (2cm / 0.79in), and additionally the wooden floors which measure another (2cm / 0.79in). Lowering the shelf would have been a huge waste of space, so I came up with this idea -rising the topmost shelf and create the necessary clearance needed (+3.5cm /1.83
