Ender 3 - Up Down Badge

thingiverse

#Badge to Assist with Bed Leveling To achieve a perfectly flat bed, simply turn the dial in the direction indicated by this badge. A visual aid is always helpful, and this badge provides a straightforward indicator for leveling your bed. This new badge replaces the makeshift scratch paper that was previously used under the printer. We've reviewed other designs, but they often suffer from limited color options, making them difficult to read against certain backgrounds. This badge stands out with its clever use of contrasting colors. I must admit, my son pointed out a few missing characters - however, you should still be able to easily decipher the instructions.
