I had some cable protectors machined from a poly-carbonate for Mega Live and the LVS32 Livescope since they have both been having issues with their connections at the base. 3D printed parts are hollow, and can absorb water and swell, so I went this route. They are $29.99 with Free Shipping in the US.
