It doesn't need to a very good conductor to be ESD safe. I have used Protopasta conductive filament to print ESD safe parts. While it may be problematic to use it as a conductor for any significant current, it's many orders of manitude more conductive than it needs to be to dissipate a static charge.

That's filament is not flexible, though.
