The stock Z-axis brackets do not hold the Z linear rods tightly or the stepper square to the frame, so I fixed it.

The Z-axis was never aligned with the frame and I determined it was some warp on the injection molded parts provided with the machine. I tried shimming behind the stepper which improved things slightly, but I wasn't satisfied. I studied the Prusa version, added a brace and some other DFM features and reprinted. Now my Z-axis is perfectly aligned with the frame and the Z-axis linear rods are firmly held in place (the hole on the stock part is oversized so they could move slightly).

You will need (8) M4 heat inserts that work in a 5.6mm diameter and 9.1mm deep hole. I used Ruthex. Here's the link to just M4 inserts, but you'd be better off getting the set for the future! Once you sink them in using a soldering iron, make sure to hold them down with something flat so they don't rise back up. You want the mounting surface to be very flat!
