Well the tubes wont have to survive. What you would have to do is print the decoration as a "sleeve" to fit over a brass tube. The brass tube will act as the buffer between the soft 3D print and the mechanisms on the inside. Then the outside of the print would be embossed further protecting the decoration from the outside.
