Works and is easier to be turned by hand than cylindrical ones.
If you intend to put it on a BIKE valve you have to cut it because it is too long (it will stop on the rubber coating).
I also recommend to print it with 0.95% XY scale, then wrench it on the valve to recut the thread and it works fine. Without it mine was just too loose and was moving up and down without engaging with the thread (even though the inner dimensions were off only by +0.05mm).
