About this 3D model
This object was made in Tinkercad. https://www.tinkercad.com/things/2e6RdPJNGqg. This is for using a dial gauge to level your CR-10 Bed. Pre-heat your bed, autohome, level one point with paper, then raise your extruder up and put the mount on. Then you can check the reading at one known level point and adjust your bed to that level at any other point on the bed. You will level your bed more accurately and faster than just using the paper method or printing a bed level test.
