This is designed in mm. If your slicer expects inches when you import this, it will be very tiny and you will have to scale it by 25.4 (2540%)

This is a simple tool to help level your Z Axis. Simply snap them onto the Z rods below the X axis and then turn the Z screws by hand until it bottoms out against the tools. Then use the machine interface to drive the Z axis up off of the tools. Store on the base when not being used.

The base takes a good bit of force to snap into the extrusion channel.

This is designed specifically for the Anet A8 Plus, but should work on any printer with a similar extrusion profile and 8mm guide rods.
