007" Edition

It says 7 inch edition in a neat way with the quote symbol refering to the english symbol meaning "inch"

The thumb prints seem to refer to a thumb being the basis of the measurement.

It looks like older Buddy v0.1.4, on the GitHub was released Buddy v1.0.0.

The LCD uses quite common ST7789v driver according to Buddy firmware - nothing special.

Bed to spacer:

  • m3x8: 9 pcs
  • Spacer lenght 6mm : 9pcs
  • screws bed to spacer: missed to measure

The screws (bed to spacer) are 3Mx3. They are also low profile countersunk Torx heads. If you were to replace them with 3Mx3 countersunk Hex, they will sit proud of the heatbed.
