I haven't gotten around to it yet but was thinking about trying a small stainless hose clamp (Google search results also brought back stainless worm gear hose clamps). Doing a very quick search just now I found a 7/32", a 5/16", and even one in black stainless steel. If one can be found that is small enough it would be very stable, could be put on either end of the body, and would be my preference over the snap on clips. For the clip portion, any number of things come to mind. Just brainstorming here but the first thought I have is an alligator clip. Even a thin metal rod like a bicycle spoke or hangar, or an old flat metal ruler, all bent creatively, might work. This idea would also be kinda' bulky too but maybe it'll lead to other ideas.
