PRINTABLE TUBES for Sunbu UP&DOWN System

This takes the amazing “UP&DOWN” system made by @djferre_garage and makes a sturdy and solid printable tube. I originally tried to convert the “stands” to 1x1" for us US dwellers and it just turned out to be too unstable. And the original printable tubes included with the file did not work as the insert portion was an ID fit, thus blocking the smaller tube from sliding inside it. So here you go! The fix and proper working printable tubes :) Assemble according to the gif below!
