Reason:

The Prusa I3 has an adjustable bed and any one of the 4 adjustable screws that hold the bed down can come loose if you do not tighten them enough. If you tighten them down to much then the bed bends making the middle a high point and all four corners low. So for printers that do not have auto calibration. This mount will allow you to make quick work of any adjustments for nozzle height in relation to the bed that may be needed before a print.
