Paper towel holder for the edge of counter

I am tired of my paper towel falling on the ground, and being that we rent, I don't want to put any tape or screw holes on the wall. I use the vise part for a couple of parts vices I have, and also a key holder that is mounted to the side of my bar countertop. The post is 38 mm diameter which fits most rolls that normally have 40 mm ID cardboard tubes. It is 238 mm tall which should fit on most printers. Reducing it would also reduce the hole in the bottom so you'd have to use a CAD program to make it smaller or bigger but not affect the hole size. The hole and post just gives it more strength for super glue to hold it. The hole is 11 mm for the 10 mm post to fit in. It seems to fit well enough for the glue to hold. The vise will widen up to 45 mm which fits most countertops. Print each piece separately or the whole thing in the STL Paper_Towel_Holder.
