Maybe, but here's the thing:  "flexible" doesn't mean that material is 
suitable.  If you take my example of a capstan, one property that's 
required is a sufficient amount of "grippiness" (there's probably an 
engineering term for it).

So, for example, polyethylene is quite soft in some forms, but is 
totally "un-grippy".   Some stuff that's grippy isn't hard enough (I 
think that's the durometer rating), e.g. most silicone elastomers.

Neoprene is obviously the ideal stuff for this; I'm wondering if this 
Sugru material has the desired characteristics.   As far as I know, one 
can't 3D print neoprene.
