This model is designed for the IKEA Omar shelving system in order to keep bottles in place. It clips into the ends of the shelves, but also works anywhere in between. It easily keeps 2 Liter bottles in place and allows you to stack several on top of each other. Of course it also works with everything else that is round.
The model should work with other wire frame shelving systems as well, but I have not tested this. If you want to test if it fits your shelves, reduce the z height in the slicer to 10 mm and print a quick test piece before you commit to a full print.
