Placeholder for new release in progress
A forum user, @DrunkenKerbalnaut, made this wonderful set of structural tubing with many switchable textures.
He hasn't been around since November, 2016, someone mentioned he had been injured.
The original thread is here:https://forum.kerbalspaceprogram.com/index.php?/topic/152597-12x-structural-tubing/
I've updated it for KSP 1.4.1, replacing the old FireSpitter texture switching code with the new stock texture switches.
