In reply to csab1978:
The 'official' kit looks a little unstable to me; seems to be attached to the base of the pot...
You might consider making a cylindrical ring to surround the top of the pot, from steel beercans, with little tabs constructed from which to hang the pot. The ring would be retained under the rolled rim of the pot (like the Caldera Cone), and locked in place by some cunning mechanism (slot & tab, for instance). If you stuck it under the cosy, that would help hold it in place, too.
You'd need to reinforce the tabs (double thickness, for instance), I suspect. Then just use some light chain or stainless wire to create a hanger.
I may have a play tonight...
