threaded tube extended

This is an extended version of the threaded tube from https://www.printables.com/model/846592-double-ended-threaded-tube. I added a coupler and an additional shorter middle section so I could get the total length to 784mm. The inside diameter is 50mm. I personally use this as an audio boom pole case. Eventually I will design another version that includes strap loops and potentially TPU inserts for the ends to help keep the boom pole from bouncing around. Alternatively cell foam would work great if cut into a circle.
