QR Code Cover with leveling knob direction for Ender 3 v2

prusaprinters

<p>I am constantly forgetting which direction to turn my bed levelling knobs after running an auto-level. I used to keep a piece of paper with the directions, but it would always end up under the printer and get sucked up by the board cooling fan. Since the QR code was unused space, I realized I could leave this convenient note on there.</p><p>The cover is 8 mm tall and the text is 1mm tall. If you print at .2 layer height, change filament at layer 40.</p>
