This kit is specifically designed for the Prusa MK2/MK3 and similar models, aiming to solve the problem that the automatic calibration function cannot work properly due to severe warping of the bed surface, helping you easily achieve accurate leveling.

The included tweezers are a time-saving tool—in my own experience, it's nearly impossible to securely clamp the stack of spacers and shims on the MK3's magnet-covered build platform.

Use method: Install a few M3 screws under the spacers on the bed surface.SpringPads

Taking my own experience as an example, the degree of warpage on the bed surface has significantly decreased by about 90%

On the X-axis, the repeatability of the dial micrometer is approximately 20 micrometers

The dial micrometer is fixed to the print piece by an M6×20 mm screw
