This is similar to the stock handle that comes with the Ender 2 Pro. The Z support hole is meant to be bigger than the Z rod so it does not restrict it's movement just like the stock support. I bought my printer used and it didn't come with it, so that is why I redesigned this. :)

(All the other designs which use a bearing to fix it into place are not the correct way to keep the Z-Rod from moving as it will cause binding and probably artifacts unless your rod is completely straight and aligned perfectly.)

This should be easily printable in two pieces. If you don't care, you can just use it without the Z-support also as it really isn't necessary.
