Made this kitchen roll holder to fit under the edge of our IKEA kitchen island. It consists of a couple of hubs that are pushed into the roll and a left and right bracket.
I've included the freecad file in case you need to tweak the size of the hubs to match the rolls where you live. Default is for 40mm rolls, which I think are standard in the UK.
I printed in PLA with 0.3mm layer height and 20% infill but anything should work, it's a fairly simple model.
