Z rod shims for Ender 3

thingiverse

To achieve precise alignment of the Z-rod with the frame, shims are essential. A mere 1mm discrepancy can be significant, but by flipping them over, you can effectively cancel out their impact. Experimenting with different combinations is likely to yield a suitable solution. Printing at the lowest feasible layer height will also help ensure accuracy. In my case, I opted for a layer height of .04.
