toilet paper holder

Toilet paper holder to be mounted on a wall radiator.
The pipes of my wall-mounted radiator have a diameter of 24mm.
Check the diameter of your radiator pipes and adjust the design if needed — simply scale it until the diameter of the circle is 0.1mm smaller than your pipe, to ensure a tighter fit.
For example, if your pipe is 30mm, the attachment circle should be 29.9mm.
