If the feed screw of the Z-axis is mounted plumb the print bed, there is nothing significant in this Mod.
However, it can be obtained by a complete vertical coupler is difficult.
So, I tried to deal with this Mod.

Still, because there is the risk of a certain amount of vertical is not made??, leading to trouble the feed screw is in contact with the bearing, it is required arrow tension adjustment.

It is not a English speaker, I am using a machine translation.
If I had a rather strange sentence, I'm sorry.

Does this make a big difference in print quality?

The Z-rod design in Portabee is quite robust, it should not shift within a single print ..

What can be of concern, is the rods slowly being pulled inwards over time,

Usually we just re-align our Portabee every so often,

However this mod addresses this, mega win! huzzah!
