Statistically, that will be the case. No extruder is going to purposely
try to make things off-size. I just wanted to put out a "heads-up" of what
could happen without things being out of tolerance from the extruder. I
think the idea of using a convenient extrusion is neat too. And don't
think I wouldn't jump on it myself if the right one were available! :-)

The part to watch out for is if things were "tight", since the linear
bearing cartridges can't take a whole lot of sqeeze before overstressing
their races.
