Concentric Bed Levelling Pattern

Updated 2023-02-18: Made the lines a twice as wide (0.8mm) for easier removal from the bed.

___________

Another bed levelling pattern for printers with 220x220 print beds, e.g., Ender 3, Kobra Go, etc., with concentric squares and small squares on corners.

The lines will allow you to gauge adhesion and the squares provide a visual of how far or squished the nozzle is to the bed.

Print at 0.20 layer height.
