Designed this one after the 3rd one that came with the bags I bought on amazon broke. Printed it mostly default settings, just enabled supports for the cord pass through and the hole top (only to get a clean result).
I've designed it for a bag roll that's 60mm tall and has a 25mm diameter. The inner tube is 18 mm. It has a 3mm gap around the roll and the inner shaft is 6mm tall and has a 5mm diameter.
I've also uploaded the fusion file, and it is parametric so you should be able to customize it also.
