4th iteration of the tube section

diameter is 34.4mm and 225mm tall, though the height is too short to use the inserts as envisioned by creator
Recommendation: either modify length as needed or glue the head parts together and then glue the base head onto the tube with it not to its end, i had mine sticking about an inch from the end of the lower head assembly. For the tail section I recommend leaving the support in and just gluing ontop of it to save another inch there.

Designed using TinkerCAD cause CAD software is scary pricy and this one is free
My print settings: CURA slicer : std layer quality (.2mm), infill 10% gyroid
