Wanhao Duplicator I3 Z Stop Spacer

I tightened my switch, but it didn't quite align with the motor bracket, causing it to malfunction occasionally. To fix this issue, I designed a small spacer to center the switch perfectly with the bracket, ensuring consistent performance every time. To replicate this solution, you'll need longer M2 screws that are specifically designed for use with 4mm spacers, which are already installed in most standard configurations. The stock screws just aren't long enough for optimal alignment.
