ultrafast XY skew checker (Prusa Mini)

My prusa Mini was skewed and it was not straightforward to fix it, so I made a little helper “model” to verify the skew in 30s.

This entry is not for fixing the XY skew (yet). If you are interested, leave a comment and I will add some tips.

It uses the original smooth build plate that has 90° lines painted on it. 

How to use:

• Put on original smooth build plate
• Print as it is
• check if 3D printed line follows the indicated line on build plate
• If needed, adjust the position of model in slicer so it is on or close to the line to see the skew better. Each printer can be bit different. In my case, the visualisation on build plate in slicer is 2mm shifted against real plate.
