Parametric roll holder

A parametric roll holder that is attached to a fridge or other magnetic surfaces to hold paper towel roll , plastic film roll or any roll you could wish to have acess to easily. You can adjust 6 parameters : the general fitment tolerance, the magnet's diameter and thickness, the roll offset from the magnets, the roll's inner cylinder diameter and the thickness of the cylinder that holds the roll.
Don't hesitate to share some feedback and to improve my model, you have the step file to do whatever you want, just post a remix mentionning me so that I can see it.
