Bolt Tungsten Holder

Was looking for a not so boring tungsten holder for welding. This is what I ended up coming up with. The inside of the container is 180mm in height, so it perfectly fits full sticks of tungsten. The ID is 20 mm, and the outside thread is M30 x 3.5. I realized that it may not be the most practical storage solution for tungsten, but I've been trying thread modeling recently and wanted to try something out that had some function.
