Micro Swiss direct drive quick X axis fix block.

When installing a new extruder, it's essential to consider how your printer defines its print space in the firmware. My CR-10 didn't allow me to make this adjustment, which resulted in the nozzle printing mid-air unless I tweaked my Marlin settings or entered additional G-code startup commands - something I wanted to avoid. This small block attaches to the flat metal section directly opposite the extruder and engages the X-axis switch without requiring further modifications. By combining this with a slight forward movement of the Y-axis switch, you won't need to include any extra G-code to account for the nozzle's new position. I printed the slot at 100% infill and trimmed it to size. The design works flawlessly and has yet to slip out of place once.
