About this 3D model
Can easily micro-adjust the height of the nozzle off the bed by turning the adjustment knob 1/8 to 1/4 of a turn. Is great when changing filaments and having to reset the Z offset. After you have used it a while you will get a feeling for just how far to turn the adjustment. Move it slightly, hit "Z Home" and see the results. Also fits HICTOP 3d printers.
