Looking for 3mm Teflon Coated Stainless Wire as a core for a mold I am
designing.

I checked McMaster and they topped out at 0.082 in. I'm looking for .118in
(3mm). Some of the lab and medical supplies go to .090 in, but that's still
too small. Suggestions?

So far the best appearing solution is to get 3mm OD (2mm ID) tube and push
some 2mm wire thru it. If its tight, great. I can make a jig to hold the
tube straight during the process.
