I created an adapter for Ikea's “VATTENKAR” table shelves, allowing me to attach a pole for the “MALA” paper roll. The holes have a diameter of 2.45 cm, and I've uploaded a parametric Fusion360 file that can be edited to fit your specific requirements. Please note, you'll need longer screws than the ones provided by Ikea
