I'm probably not the first person to think of this, but it's an interesting concept that occurred to me a while back. Consider a threadless ball screw like this:

I'm thinking 3mm ABS is probably the only filament this will credibly work with. You need to get some bite and you need some reasonable thickness to get three bearings in place adequately. Basically HAVE to use tilted flanged bearings to get everything to fit close enough, and get a decently sharp edge, and survive the axial load.
