NATO emblem keychain

This is a 60mm circle keychain with the NATO/OTAN logo on it.

It is designed to be printed on a single-extruder printer like the Ender 3 or Anycubic i3 mega s (which I used to print). You will need to:

1. In CURA, go to extensions>post-processing>modify g-code.
2. Set layer height to 0.08mm and 0.16mm for the first layer.
3. Add 3 "filament change" scripts for layers 3, 5 and 6. (check the screenshots)
4. Slice it and send it to print with the WHITE filament.
5. When the printer stops at the 3rd layer, change filament to BLUE and unpause it.
5. When the printer stops at the 5th layer, change filament to BLACK filament and unpause it.
5. When the printer stops at the 6th layer, change filament to BLUE filament and unpause it.

The layer of black filament will make the blue layers that come afterwards look darker than the ones coming after the white layers.

Make sure you use filaments that at least have the same melting point (ideally from the same manufacturer.
