I bought a set of 5/8BSP taps and die just because.
I made these plugs today to keep dust and grime out and to hold on to the filling O-ring (that sod has escaped several times and gone AVOL forever).
Some POM and some lathe time later.
A little bottle "pic"

That's some good stuff. I've done some woodwork over the years but never did anything with metal. I admire your skill. Of course you know now somebody is gonna want one of those. 
I don't have a bottle gun - yet.

POM is a generic easy to machine plastic!
I will do them but if you can get a state side firm with a CNC lathe to do them prices will plummet!
If you want them bad then PM me and i'll do what you want and add shipping, no problem.

Hi Chickenthief
I was admiring your work and liked the concept.
I was searching for a source of something similar in Australia.
I came across these https://www.divegearexpress.com/dgx-threaded-dust-plug-for-din-valve-plastic
An American site and shipping costs were ridiculous so out of the question.
Thing is this warning from the site :
"The screw-in type DIN valve dust plugs are very popular, but there is a safety concern. The early designs from when DIN valves were first introduced in to the U.S. were solid and a real safety hazard, but today the dust plug designs have a pressure relief vent hole to avoid trapping gas pressure. However, if you suddenly open the valve wide enough while the dust plug is in place, then it's possible the tank pressure will still be enough to overwhelm the relief vent and forcefully eject the dust plug from the valve. The force of the tank pressure may even be enough to cause the plug to become one or more pieces of shrapnel that could injure the diver or other bystanders. If you use DIN valve dust plugs, even the vented design, always make sure the valve is closed tightly and never open a valve while the dust plug is in place. If you still have one of the early un-vented dust plug designs they should be discarded."
Do you have a pressure release in your design?

No and thats ok because they vere ment for me.
But i see no problem in drilling a hole along the center and put in a bead of styrofoam or the like to keep out dust.
