(Yes, I mean the little black rod in the non nib end of the collector to keep the collector opened.)
I have two suggestions so far, pencil lead from El Zorno and a very ingenious one from PenFisher of the retail price tag nylon strings shaped like this I----------------I. (The dotted line is a solid nylon string in real life.)
This is ingenious as if you grab one of the T ends and yank it, you'll stretch out and reduce the diameter of the string such that you just snip down it til you find a section the correct diameter for the micro channel. (I've got a clear one, but picky butt me will likely have to find a "correct" black price tag "string" if someone doesn't have a better idea.)
What do you use?
