Threaded box extender for bagpipe container

prusaprinters

I gave my Nephew an empty cat litter container for his small bagpipes.  One pipe was a little too long to fit right.I decided to see if I could 3d print an extender.  The extender needed to be solid enough to protect the pipe.2nd issue was that the container turned out to make a good stool so the extender needed to be easily removable.I designed it so a hole could be cut in the lid of the container and the extender threaded in in a few seconds.  Also could be removed as quickly.I had only a little problem with the threads that needed a little polishing of edges and now they thread easily.Feel free to do what you want with this or suggest mods.
