Recently acquired an FN303 - but it came without a tank... Which is mostly a good thing as I believe the original tanks dumped about 2500 PSI into the valve.

In modifying this for paintball, I want to switch over to a standard ASA sort of arrangement for convenience... 550 - 850 psi input pressure on a 13ci.

That said - this leaves me in a bit of a pickle as to how to interface with the original mounting location without a tank with the clamped on block used to do so.

What I would like to do is 3D print something that will click into that location with a clamp around the 13ci - either a metal band clamp or perhaps a rubber tension strap of some sort.

I hope to be able to modify this: http://www.thingiverse.com/thing:1068784 with the wedge block to interface with the launcher.

Thoughts? Any info is greatly appreciated.
