About this model

Don't forget to hit the like button if this helps you :) Improved calibration prints with minor modification to connect all the printed squares for easy removal from the bed. (uses a 0.4mm line width)These prints work seamlessly with the instructions with the original model linked below: When you want to fix a specific spot on the mesh use the STLs which have only the edge corner or edge middle square. Its a 1min print and you can rotate it in slicer to cover any of the 8 outer squares of a 3x3 print. Really good if you have a particular spot you want to perfect and want to iterate quickly and don't want to reprint the entire 3x3 grid.
