Z-Lower + Z-Motor Improvements (25mm)

improve the Z-Axis stability and make it much easier to get the two parts exactly parallel because they mate nicely together. No more guesswork.

There is enough space between the parts so that you can still tighten the aluminum coupler on both ends.

As a little extra, there are 4 holes on the side. These allow you to fix the parts to the tube with bolts and nuts. This is entirely optional. I haven't tried it myself yet. You'd probably also want to use some sort of nut trap on the inside
