Once I convinced my friend that the noise wasn't the result of some problem with the stepper motors and seemed to be greatly amplified at resonant frequencies, we quickly brainstormed a couple of fixes involving various extrusion fills and RTV silicone was at the top of our list. Great minds think alike, I guess. :-)
My recent experiments with RTV silicone lead me to guess that the silicone would cure a couple of inches on the ends where it was exposed to the air, and the inner fill either wouldn't cure at all or would cure over the course of a year or so. In this application, it probably wouldn't matter. The dampening would be provided by cured or uncured silicone rubber. Strange Coincidence - I was taking another look at the RTV silicone on the McMaster-Carr website (for my upcoming silicone rubber 3D printing project) when your email arrived in my Inbox.
