Magnetic Shop towel holder
thingiverse
didn't see a design that worked with magnets so I created my own. Just print two, throw magnets of your choice in that fit (I used 3mm H x 59mm L x 9.3mm W bar neo magnets but circular would work as well and I'm going to glue mine in) and stick them where you need with the roll between them. I'm printing mine now so I will update pics after.
