This multipurpose shelf can be used anywhere, I designed it for my IKEA EKKET cabinet to use the space better for our shoes. You may need rectangular (1x1cm) or circular dowels (d=1cm) in desired length. For a longer shelfs I recommend to use one end plate in the middle. If you do not want to use wooden dowels than simply in slicer create an object but do not forget to use clearances (rectangle 0,98x0,98 cm - for example).
