they seem awefully stiff. you generally want some flexability in the couplers.

Not 100% sure about the AO-100, but for the TAZ I printed (and posted) these. they are nice and flexible in Nylon. [http://www.thingiverse.com/thing:117950](http://www.thingiverse.com/thing:117950)

but there are other options too.
