One of my early projects when I was first learning to turn and mill metal was a fire piston. Being metal, it was able to be smaller that the one you built…but not nearly as nice looking. It did have a screw-off cap on the end to store some char cloth. It worked well enough and I gave it to a friend of mine who was an avid backpacker. It’s got advantages to other fire started, or so I’m told. I’ll see if I can dig up some old pics of it, but not sure if I’ve got any. Great project! Nicely done.
