This is an X axis height adjustment tool designed for the CR-10, especially if the Z axis upgrade is installed. Nevertheless, it can be certainly used for other 3D printers. You need to print two tools to use it.
- Move the extruder in the middle on the X-axis.
- Put the adjustment tools on the bottom frame on each side of the X-axis, as shown on the main photo.
- Turn the lead screws manually until the X-axis sits on the adjustment tools on both sides.
- Remove the tools and adjust your bed.
The tool is about 100 mm in height, 21 mm deep and 10 mm wide.
