Nitrous Express15930 Nitrous Bottle Stand

When I tried to use this stand, I re-discovered that cylinder cap threads are not fully standardized. There are at least two different thread pitches in use. This fits one of them - not the other. Would have been nice if they designed it with a thicker collar and set screws to make it universal, rather than only fitting half of the cylinders out there. But it works for the ones it fits.
