Parametric Tube Stand

This is a parametric tube holder. Its original intent is to hold falcon tubes, but any cylindrical object will work, e.g. test tubes or fountain pens, etc. Features: Low MaterialSturdyAlignment/Drain Hole in the bottom2 Versions: One with viewport, one without. Trade-Off between being able to see graduations at the bottom and stability. The viewport version is still very sturdy, I recommend using that one.
