how to make a custom o-ring for shower deviator
I am sure there must be a way to make a replacement either out of rubber or silicone either by 3D printer or some kind of mold.
I would appreciate any kind of help - either someone with a 3D printer who could make one or a mold for silicone or melted rubber.
I don't mind paying for this as I'm sure it would cost considerably less than replacing the whole magilla.
I'm thinking of the kind of rubber used for bottle stoppers that empty air from wine bottles; or some way to make this o-ring.
The dimensions are in the attached images. I an furnish more images if necessary and contact info.
