Rack Shelf Paper Roll Holder

Wanted a place to have a paper towel roll on the garage. Seemed a good idea to give the holes on the rack some use.Don't know if the holes on the racks are usually a standard, so before spending time and filament, check if the lower edge of the 2 holes that were this will be installed have a 121 mm distance and if the holes have a 10 mm diameter on top and a 6mm on the bottom (drawing for guidance).The printed one was a bit wobbly, it could stand the roll but I thickened the main structure to make it stronger.Made it a with a extension (tight fit), is not mandatory only if you wish that it reaches more the top of the roll.Feel free to remix, change, whatever and share....step file and .f3d file included.
