Ender 5 Z-Axis stabilizer

Based on the design by wastr3l, I recreated the Z-Axis stabilizer and increased the height by 5mm to cover the whole width of the 2020 rail. Also added a few more chamfers to the design. Otherwise it is functionally exactly the same as the original.

Requires a 608 ball bearing, two M4 screws and two M4 2020 rail t-nuts
