Z Axes Holder with Ball bearings for ALUNAR M508

I have made this 2 Z Axes holder for more stability and lower vibrations on the Printer.
It works very well for me.
The Hole for the bearings are 22mm the deep are 8mm.
Bearings are 608ZZ.
On the side is a Hole for an M3 Screw to fix the 8mm Guide shaft.
Using PLA.
Feel free and test it yourself :D
