Kudos to areeve20 for providing an excellent design to get my keyboard and trackpad off my desk. I recreated the design to fit IKEA Expedit and Lack shelves so I can hang my other keyboard and trackpad that I use for home theater server. Design is provided with and without screwhole for securing. On Expedit and Lack shelves, it is snug pressure fit, but these will also fit on Kallax system shelves with a screw to secure them. Added a finishing cylinder to the ends of the clip, and a subtle bevel to the edges as a nod to IKEA style.
