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
